889: Fix clippy warnings r=MarinPostma a=TaKO8Ki

Good day!

Since `cargo clippy` showed two warnings like the following, I've fixed them. This is a small PR.

```sh
warning: use of `ok_or` followed by a function call
   --> meilisearch-core/src/database.rs:185:18
    |
185 |                 .ok_or(Error::VersionMismatch("bad VERSION file".to_string()))?;
    |                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: try this: `ok_or_else(|| Error::VersionMismatch("bad VERSION file".to_string()))`
    |
    = note: `#[warn(clippy::or_fun_call)]` on by default
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#or_fun_call

warning: useless use of `format!`
   --> meilisearch-core/src/database.rs:208:59
    |
208 |                         return Err(Error::VersionMismatch(format!("<0.12.0")));
    |                                                           ^^^^^^^^^^^^^^^^^^ help: consider using `.to_string()`: `"<0.12.0".to_string()`
    |
    = note: `#[warn(clippy::useless_format)]` on by default
    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#useless_format

warning: 2 warnings emitted
```
