Actions - Warning Annotations

[ghnp5]

This might be related to #23721, which implements a Job Summary section.

In the same section (or an adjacent section), we'd have a place for Annotations.

So, if we run this on GitHub Actions:

echo "::warning file=app.py,line=10,col=5::Code formatting issues detected"

The annotation will appear like this:

And it links to the Commit that triggered the action/workflow, scrolled to that file and line directly.

Line 100 in e0aacc7

### Problem Matchers

), but I could not find an issue tracking their addition/implementation.
