Subject: [PATCH] .github: check-metadata: new workflow

Add a GitHub Actions workflow to run the maintenance script
"check-metadata.sh" on pushes to branch 'main' and on pull requests
which target branch 'main'.

I'm not sure if `concurrency:` is needed.

I used the following GitHub Actions files as inspiration:

- For overall structure:
  - https://github.com/curl/curl/blob/c39585d9b7ef3cbfc1380812dec60e7b275b6af3/.github/workflows/linkcheck.yml
- For job naming and Bash script launch:
  - https://github.com/rybak/intellij-copy-commit-reference/blob/47a64c7408d854f73fa59a053d9346c27122bafe/.github/workflows/build.yml
