Automations: Create changes only zip on release

[luke11brown]

What is the current situation?

https://github.com/VATSIM-UK/uk-controller-pack/blob/main/.github/workflows/Create%20ZIP%20on%20release.yml
creates full ZIP on release.

Changes only created every 28 days using git command
Git diff --diff-filter=d --name-only -z [Commit at last release]^ | xargs -0 git archive -o changes_only.zip HEAD --

What is the proposed change?

Create workflow in similar vein to existing to create a changes only zip on release. The workflow must do the following:

• Copy README from docs folder
• get release tag and use it in created zip title
• include all changed files since last release, excluding .prf files that only have the sector file location line changed.
• exclude .py files
• upload zip as release asset

Possible solution
git diff --diff-filter=d --name-only -z [Commit at last release]^ | xargs -0 git diff [Commit at last release] HEAD -- | awk '/^\+\+\+ b/ {print $3}' | grep '\.prf$' | xargs -I {} git archive -o changes_only.zip HEAD --
