475: Bump tokenizer r=Kerollmops a=irevoire
This PR bump the tokenizer in v0.2.9 which fixes an issue we had with lindera where reqwest was used with openssl (which was breaking our benchmarks).

476: Rollback meilisearch-tokenizer version r=Kerollmops a=irevoire
Lindera often fails to download some data from google drive we can’t compile consistently meilisearch / milli.
We can’t bump to the latest version (that moved out of google drive) either because lindera uses reqwest with openssl with no way of configuring it our benchmarks were not able to run. The latter issue should be fixed by https://github.com/lindera-morphology/lindera/pull/164.

472: Remove useless variables in proximity r=Kerollmops a=ManyTheFish
Was passing by plane sweep algorithm to find some inspiration, and I discover that we have useless variables that were not detected because of the recursive function.

468: Add a new error message when the filterableAttributes are empty r=Kerollmops a=brunoocasali
Fixes https://github.com/meilisearch/meilisearch/issues/2140
Is there a good way to reduce de duplication here? Maybe adding a shared function? I don't know the best and idiomatic way to do that, I appreciate any tip!
Another doubt is related to the duplication of the calling:
```rs
// filter.rs:373
FilterError::AttributeNotFilterable {
attribute,
filterable: filterable_fields.into_iter().collect::<Vec<_>>().join(" "),
},
```
and
```rs
// filter.rs:424
return Err(point[0].as_external_error(FilterError::AttributeNotFilterable {
attribute: "_geo",
filterable: filterable_fields.into_iter().collect::<Vec<_>>().join(" "),
}))?;
```
I think we could make the `filterable_fields.into_iter().collect::<Vec<_>>().join(" ")` directly into the error handling like the sortable error. I made it into the last commit, if this is something to avoid, let me know and I can remove it :)

467: optimize prefix database r=Kerollmops a=MarinPostma
This pr introduces two optimizations that greatly improve the speed of computing prefix databases.
- The time that it takes to create the prefix FST has been divided by 5 by inverting the way we iterated over the words FST.
- We unconditionally and needlessly checked for documents to remove in `word_prefix_pair`, which caused an iteration over the whole database.

This PR upgrade and updates this crate's dependencies but first, it removes three dependencies that we don't use anymore. I used [cargo udeps](https://github.com/est31/cargo-udeps) to upgrade them ⬆️

457: Avoid iterating on big databases when useless r=Kerollmops a=Kerollmops
This PR makes the prefix database updates to avoid iterating on big grenad files when it is unnecessary. We introduced this regression in #436 but it went unnoticed.
---
According to the following benchmark results, we take more time when we index documents in one run than before #436. It looks like it is probably due to the fact that, now, instead of computing the prefixes database by iterating on the LMDB we directly iterate on the grenad file. Those could be slower to iterate on and could be the slowdown cause.
I just pushed a commit that tests this branch with the new unreleased version of grenad where some work was done to speed up the iteration on grenad files. [The benchmarks for this last commit](https://github.com/meilisearch/milli/actions/runs/1927187408) are currently running. You can [see the diff](https://github.com/meilisearch/grenad/compare/v0.4.1...main) between the v0.4 and the unreleased v0.5 version of grenad.

461: Add a new error message when the `valid_fields` is empty r=curquiza a=brunoocasali
I've created a test case to handle the new error formatting behavior, but I'm not sure if:
- this is the right place to add the test?
- this is the best way to test this behavior?
And I'm not sure also regarding the `match` implementation, is this something required? Or maybe just an `if` statement is ok as well?
I left the two messages literally without "reusing the prefix" in the implementation because I think this could help the "searchability" of the error in the future.

462: cli improvements r=Kerollmops a=MarinPostma
a few improvements:
- use bufreader to load documents, so the loading of the document doesn't appear on flamegraphs
- set default db path to current directory so the `-i` flag can be omitted.

459: Update heed link in cargo toml r=Kerollmops a=curquiza
Since grenad and heed have been moved to the meilisearch orga, this PR changes the link.
This is a minor change since GitHub handles automatically the redirection. This PR is only for consisitency.

456: Remove useless grenad merging r=Kerollmops a=Kerollmops
This PR must be merged after #454.
This PR removes the part of code that was merging all of the grenad Readers merging that we don't need as the indexer should have merged them and, therefore, we should only have one final grenad Reader. We reduce the amount of CPU usage and memory pressure we were doing uselessly.
`@ManyTheFish` are you sure I can skip merging the `word_docids` database?
Here is the benchmark comparison with the previously merged PR #454:

```
And the comparison with multi-batch indexing before #436, we can see that we gain time for benchmarks that index datasets in multiple batches but there is _so much_ variance that it's not clear.
