@Sergio-IME hi, thanks for the improvement!

I'm approving the PR as the implementation is the same as for the other formats.
Would be also great to add integration tests to somewhere in https://github.com/ansible-collections/community.mysql/tree/main/tests/integration/targets/test_mysql_db/tasks.
Would you be interested in doing it in another PR (or in this one if you want)?
Anyway, I don't see it as a blocker in this particular case.
Approved.

I don't think we test other compression algorithm either. So I'm merging this PR. Thanks @Sergio-IME for your contribution!
Thought it could be great to add integration tests that validate the compressed archive can restore tables once imported. This could be done in another PR.

Thank you so much for adding this @Sergio-IME 🙏

I think we could release after #697 if everybody is happy so user will get the features
