I apologize for all the commits. Workflows are not the easiest thing to test.

Here is a workflow run for creating a new release (when the release version was updated): https://github.com/ReenigneArcher/Sunshine/actions/runs/1683355353

And here is a workflow run when the release version was not updated in the CHANGELOG.md (this should also be caught when the PR is created against the master branch): https://github.com/ReenigneArcher/Sunshine/actions/runs/1683445817

And here is an example of the release: https://github.com/ReenigneArcher/Sunshine/releases

This needs a little tweaking on the create release action due to the multiple steps, it fails on all except the first build. I have an idea to fix it though.

Updated Examples:

PR into nightly branch
https://github.com/ReenigneArcher/Sunshine/actions/runs/1685200094
-No check on CHANGELOG.md
-Build each version
-Package everything except Fedora
-Upload artifacts

PR into master branch
When the release version from the changelog matches the latest released version: https://github.com/ReenigneArcher/Sunshine/actions/runs/1685245727/attempts/1
-Intentionally fail the workflow (gives an opportunity to fix the CHANGELOG.md before accepting the PR)
-Build each version
-Package everything except Fedora
-Upload artifacts

Release version in changelog was updated and does not match latest released version: https://github.com/ReenigneArcher/Sunshine/actions/runs/1685245727/attempts/2
-Same as attempt 1 except workflow passes beyond changelog check

push into master branch
https://github.com/ReenigneArcher/Sunshine/actions/runs/1685294883

• Harder to fix anything at this point so:
  • The check on changelog is done earlier when the PR is made into master

Example of Created Release
https://github.com/ReenigneArcher/Sunshine/releases/tag/0.0.0

Not an expert on the GitHub actions side, so all I can say is LGTM for the workflow side of things
