4945: Add swedish in default pipelines r=dureuill a=ManyTheFish
# Summary
## Fix Swedish support
In Swedish the characters `å`/`ä`/`ö` are completely different than `a` or `o` and should not be normalized as the same character.
because the Swedish specialized pipeline was not activated by default, these characters were normalized even with the settings:
```json
{
"localizedAttributes": [ { "locales": ["swe"], "attributePatterns": ["*"] } ]
}
```
## Update Charabia adding German support
German segmentation will now be activated using the setting:
```json
{
"localizedAttributes": [ { "locales": ["deu"], "attributePatterns": ["*"] } ]
}
```
# TODO
- [x] Activate Swedish Pipeline
- [x] Add a test to avoid future regressions
- [x] Update Charabia

- Remove `hybrid.embedder` boolean from analytics because embedder is now mandatory and so the boolean would always be `true`
- Rework search kind so that a search without query but with vector is a vector search regardless of (non-zero) semantic ratio
