3670: Fix addition deletion bug r=irevoire a=irevoire
The first commit of this PR is a revert of https://github.com/meilisearch/meilisearch/pull/3667. It re-enable the auto-batching of addition and deletion of tasks. No new changes have been introduced outside of `milli`. So all the changes you see on the autobatcher have actually already been reviewed.
It fixes https://github.com/meilisearch/meilisearch/issues/3440.
### What was happening?
The issue was that the `external_documents_ids` generated in the `transform` were used in a very strange way that wasn’t compatible with the deletion of documents.
Instead of doing a clear merge between the external document IDs of the DB and the one returned by the transform + writing it on disk, we were doing some weird tricks with the soft-deleted to avoid writing the fst on disk as much as possible.
The new algorithm may be a bit slower but is way more straightforward and doesn’t change depending on if the soft deletion was used or not. Here is a list of the changes introduced:
1. We now do a clear distinction between the `new_external_documents_ids` coming from the transform and only held on RAM and the `external_documents_ids` coming from the DB.
2. The `new_external_documents_ids` (coming out of the transform) are now represented as an `fst`. We don't need to struggle with the hard, soft distinction + the soft_deleted => That's easier to understand
3. When indexing documents, we merge the `external_documents_ids` coming from the DB and the `new_external_documents_ids` coming from the transform.
### Other things introduced in this PR
Since we constantly have to write small, very specialized fuzzers for this kind of bug, we decided to push the one used to reproduce this bug.
It's not perfect, but it's easy to improve in the future.
It'll also run for as long as possible on every merge on the main branch.

3836: Remove trailing whitespace in snapshots r=dureuill a=dureuill
# Pull Request
## Related issue
No issue, maintenance
## What does this PR do?
- Remove trailing whitespace in snapshots by adding a trailing `|` at the end of lines that would previously end with fixed-width integers
- This allows contributors whose editor is configured to remove trailing whitespace not to modify the tests when changing an unrelated part of the file containing the tests

3813: Fix SDK CI for scheduled jobs r=curquiza a=curquiza
The SDK CI does not run for the scheduled job (`cron`) every day, and only works for manual triggers.
I added a job to define the Docker image we use depending on the event: `worflow_dispatch` = manual triggering, or `scheduled` = cron jobs

3789: Improve the metrics r=dureuill a=irevoire
# Pull Request
## Related issue
Implements https://github.com/meilisearch/meilisearch/issues/3790
Associated specification: https://github.com/meilisearch/specifications/pull/242
## Be cautious; it's DB-breaking 😱
While reviewing and after merging this PR, be cautious; if you already have a `data.ms` and run meilisearch with this code on it, it won't work because we need to cache a new information on the index stats (that are backed up on disk). You'll get internal errors.
### About the breaking-change label
We only break the API of the metrics route, which does not pose any problem since it's experimental.
## What does this PR do?
- Create a method to get the « facet distribution » of the task queue.
- Prefix all the metrics by `meilisearch_`
- Add the real database size used by meilisearch
- Add metrics on the task queue
- Update the grafana dashboard to these new changes
- Move the dashboard to the `assets` directory
- Provide a new prometheus file to scrape meilisearch easily

3788: Use `RoaringBitmap::deserialize_unchecked_from` to reduce the deserialization time r=irevoire a=Kerollmops
This pull request replaces the `RoaringBitmap::deserialize_from` methods with the `deserialize_unchecked_from` to avoid doing too much checks. We know the written bitmaps are valid as we do not disable the checks during the indexation phase.
I did a small test with #3780 and discovered that the deserialization time changed from 32% to 9.46% when using these changes. It seems it was low-hanging fruit hidden behind a leaf.

3786: Consistently use wrapping add to avoid overflow in debug when query s… r=dureuill a=dureuill
# Pull Request
## Related issue
Fixes https://github.com/meilisearch/meilisearch/issues/3785
## What does this PR do?
- Some of the code paths would erroneously use the default addition operator that has the semantics that "overflow is an error, checked at runtime in debug" instead of the intended "overflow is expected" semantics that this code use (this code is using `u16::MAX` as a sentinel). This PR makes it so the wrapping add operator is used everywhere.
