Merge #4912

4912: Allow Meilitool to dumplessly, offline upgrade v1.9 -> v1.10 in some conditions r=Kerollmops a=dureuill

- bail early if the DB contains at least 1 REST embedder, providing the list of detected REST embedders, and without modifying the DB
- Might depend on the feature set that meilitool was compiled with and the featureset that the Meilisearch that created the DB was compiled with 💀. In case of runtime error, try again with a different feature set (passing or not passing `-p meilitool` when building after a `cargo clean`)
