Steps to release a new GAM version

In a final commit before release:
- src/gam/__init.py __version___ value should be updated to the new version.
- src/GamUpdate.txt should be updated with a high-level changelog.
- wiki/GamUpdates.md should be updated with same high-level changelog.
The build.yaml Github Action for final commit should complete successfully and creating a new dated Draft release.
- We should NEVER upload release files manually. Only release files automatically created and attested as created by the Github Action should be used.
Edit the Draft release:
- Create a new tag with the format: vN.NN.NN where N.NN.NN is the GAM release version.
- name the release "GAM N.NN.NN" where N.NN.NN is the GAM release version.
- Include the changelog details for the new version in details.
- leave "Set as pre-release" unchecked and "Set as the latest release" checked.
- Publish the release.

TODO: Release Process Improvements

copying changelog between GamUpdate.txt, GamUpdates.md and release description is manual and tedious. Automate it.
copying version string from gam/init.py, changelogs and release details and tag in manual and tedious. Automate it.
See if we can block releases with binaries not uploaded by GitHub Actions to further secure release pipelines.
