Simplify ignored paths.
Opt out of PowerShell telemetry.
Delete Wine VS2017 removal comment.
Make checkout fetch-depth 0.
Capitalize CMake.
upload-artifact:
 Update to v2.
 Simplify path. (/** isn't needed)
 if-no-files-found: error.
release:
 Switch to ubuntu-20.04.
 Prettify if condition.
 Use download-artifact v2;
  This allows all artifacts to be downloaded.
 Iterate through artifacts instead of manually naming/hard coding them.
 Switch to create-release v1;
  This tag is the latest version.
 Use hub release instead of upload-release-asset.
