Is your enhancement related to a problem? Please describe.

https://github.com/github/vscode-github-actions is the official VSCode extension for GitHub action support. It adds syntax highlighting and intellisense to yaml workflows. (and updates the icons in the file explorer)

However, it also changes the "language" of the files for github-actions-workflow (GitHub Actions Workflow)

Describe the solution you would like

Register redhat.vscode-yaml as a formatter for github-actions-workflow files
