chore: execute releases via git-sv (#865)

Following the creation of the changelog via `git-sv`, the release process can also be simplified.

The new approach only requires to call `git sv tag` from a Maintainer with write access to the repo.
This will create and push the tag.
The release notes and subsequent Gitea release will then be created by the new workflow job.
