No

Describe the solution you'd like

Utilize the GitHub Actions Job Summary feature we could output the markdown as GitHub friendly markdown in the GitHub Action output.

Describe alternatives you've considered

We currently allow pushing the result to a Discussion or Issue. We definitely need to keep this but we can also output to the GitHub Actions screen

Looking at the docs, do you think a cat contributors.md >> $GITHUB_STEP_SUMMARY in the action workflow work? Or were you thinking of building this into the python code?

@zkoppert good question. TBD.
