Merge #490

490: Enforce labelling for the PRs r=curquiza a=curquiza

- Enforce one of the following labels to make the CI pass: `no breaking`, `DB breaking`, `API breaking` (milli API, not the Meilisearch API of course), or `skip changelog`. This new CI is now `Required` in the GitHub settings for merging a PR.
- Adapt the release drafter to these new labels
- rename `skip-changelog` into `skip changelog` according to the new label name
