chore: automate development version and release generation (#772)

This change introduces a GitHub Action to automate release creation, including
proper tagging and automatic addition of a development marker to the version.

A hash is also appended to development versions to make their state easier to
distinguish.

Tests and release documentation have been updated to reflect the revised
release workflow. Several files now retrieve the current version dynamically.

The test --full-run option has been rename to --finalize to make
clear it is to do commit finalization testing.
