Use conventional commits

[jgsogo]

After #43 we are using release-plz to create and publish our releases.

This tool can write changelogs automagically if we adhere to conventional commits:

• we can enforce them using some GH action like https://github.com/marketplace/actions/conventional-commit-in-pull-requests
• enforce them via comitizen on the user side, enabling it as a pre-commit msg hook: https://commitizen-tools.github.io/commitizen/tutorials/auto_check/

I would not check this as part of pre-commit.
IMHO enforcing conventional commit message in merge commits (real merges or squashes) should be sufficient.
This gives developers more flexibility to commit often.

I like the approach of https://github.com/marketplace/actions/conventional-commit-in-pull-requests :-)

Yes. Sure, we are only interested in the PR title.
