Add a new workflow file(for testing purposes only)for a github action worflow that automatically generates release notes in a nice format from commit messages (and pr's too perhaps?). The solution should be simple and by default take into account commit message prefixes such as "chore:", "fix:", "feat:", "docs:", "docs(readme):" etc.

A similar automated solution should be implemented(using some other extension if needed. Otherwise in a simple way) to get all these release notes together in a single changelog md file, using a github action that automates the process in a simple way.

The github actions chosen from the GitHub actions marketplace should be fairly well-known, well built and fairly maintained.

The new file with these new workflows, should not actually be triggered on pr or such, but only manually on workflow_dispatch with the appropriate inputs(such as release versions etc). It shouldn't either make any actual changes or additions, only print out the expected release notes and/or full changelog.
