CI Runs and fails for updates of main branch of forks

[iamjpotts]

Is it desirable for the GitHub workflows to run on a main branch of forks?

For example, this is a failing run on the main branch of my fork. The run of build-and-deploy-the-docs was triggered by syncing my main branch with this repo's main branch.

It's definitely not intended to run on the main branch in forks.
