feat(github-actions): automate tagging and release process

Update GitHub Actions workflow to automatically tag and release based on
the latest main branch. The tagging process now checks for existing tags
on the current commit and determines the next version accordingly.Additionally, the release process includes generating a changelog from
git logs since the last release.

BREAKING CHANGE: Manual tagging after tests is replaced with automatic tagging and release process. Ensure that the new process aligns with your deployment strategies.
