devops: Research changelog generator for release management

[gustavovalverde]

Building the changelog file for new releases might get harder overtime if there's a lot of new changes, or if a release schedule was skipped. Manually getting this information from the PRs body can get cumbersome, and some information we might miss important information to add to the changelog.

As we're using conventional commits, we might want to inherit some specifics to make it easier to classify this information, for example for Breaking Changes or others: https://www.conventionalcommits.org/en/v1.0.0/

We can also use a changelog generator that benefits from using conventional commits:

• https://git-cliff.org/
• https://github.com/conventional-changelog/conventional-changelog
• https://github.com/marketplace/actions/release-changelog-builder

Or using other information (like tags, labels, etc.):
