POC: tag/release cycle and changelog generation

POC to test an automated tag/release cycle based on conventional commits, and generate a changelog.

Uses:

• Conventional Changelog Action: This action will bump version, tag commit and generate a changelog with conventional commits.

---

Conventional Commits (Angular):

1. fix: a commit of the type fix patches a bug in your codebase (this correlates with PATCH in semantic versioning).
2. feat: a commit of the type feat introduces a new feature to the codebase (this correlates with MINOR in semantic versioning).
3. BREAKING CHANGE: a commit that has the text BREAKING CHANGE: at the beginning of its optional body or footer section introduces a breaking API change (correlating with MAJOR in semantic versioning). A BREAKING CHANGE can be part of commits of any type.
4. Others: commit types other than fix: and feat: are allowed, for example @commitlint/config-conventional (based on the Angular convention) recommends chore:, docs:, style:, refactor:, perf:, test:, and others.
