Introduce Conventional Changelogs to the repository
We want to have nice Changelogs
like the ones from Conventional Changelogs when there's a version bump of the repository.
This means that every time we bump
a new version of our CSS library, it should update the CHANGELOG.md file with all the commit messages (and changes) included in this release.
The Conventional Changelog should be in the end an npx
or npm (package.json) script
