Merge #3212

3212: Setup COMMIT_SHA and COMMIT_DATE build args in the Docker image r=curquiza a=brunoocasali

GitHub auto-closed my PR when I synced changes with my remote 🤷‍♂️  https://github.com/meilisearch/meilisearch/pull/2550
The last PR #3205 were closed to help `@curquiza` test the CI.

In any case, the summary of changes is quite similar:

- Fix `git` usage from my last attempt (when you use `actions/checkout`) you get the `git` command to use.
- Add the `build-args` definition from https://github.com/docker/build-push-action#inputs, which is supposed to work precisely as docker build `--build-arg`. 

Fixes https://github.com/meilisearch/meilisearch/issues/2028

The result will be like this:
