Enable workflow actions on a user's fork of this repo

[khiron]

I believe users will be able to run the github action build_docs if they select the option settings/actions/general/Action permissions = Allow all actions and reusable workflows

Select the Actions tab and select that they understand and enable workflows

And then commit at least once in the /.github/workflows folder. Perhaps we should have a contributors.txt file there and have people add their name and commit the change to the repo and do a pull request when they onboard.

but how does that work with the final step which will publish to github pages? How will they see the result of their edits?
