Automatically create new release and create/attach add-on .zip on new tags (i.e. version bumps)

[jonmatthis]

Create a GH Action that:

• On new tag
  • Create .zip from [repo-root]/freemocap_blender_addon/ folder
  • Create new Release (named v[VersionTag] Release or something)
  • Paste boiler plate instructions to Patch notes (see v1.3.0)
  • Auto generate Release notes

Bonus!

• Create and run build tests, including:
  • Install .zip to blender via subporocess blender ... call
  • Process freemocap_test_data to produce a freemocap_test_data_processed_with_[VersionTag].blend file, and attach to the release

Current attempt (broken) - https://github.com/freemocap/freemocap_blender_addon/blob/main/.github/workflows/create_addon_install_zip.yaml

This GH Action is supposed to work, but it needs to pull the latest tag name for the release name, I think (will post error below)
Example of failed run: https://github.com/freemocap/freemocap_blender_addon/actions/runs/10182600886

Error:

Validation Failed: {"resource":"Release","code":"custom","field":"pre_receive","message":"pre_receive Sorry, branch or tag names consisting of 40 hex characters are not allowed."}, {"resource":"Release","code":"custom","message":"Published releases must have a valid tag"}

Presumably about Line 33 of the workflow .yml:

freemocap_blender_addon/.github/workflows/create_addon_install_zip.yaml

Line 33 in 8c23770

release_name: Release ${{ steps.get_tag.outputs.tag }}
