GH Workflows: Include dash delimiter for projects

[MaoShizhong]

Because

In #28843, the project lint workflow needed to include _ in the path filtering as for some reason it was matching false positives without it (still not entirely sure why). But it seems not all lesson files use snake case - some use kebab case (like the lesson files in foundations/html_css) and so cause projects to trigger the lesson lint workflow instead (seen in #28983).

It's less disruptive to just include - in the project workflow path filtering than unify the file name casing (which would require changes to the website repo lessons list too).
