Trigger website rebuild when gorefs.yaml changes

[pkalita-lbl]

Re: #2235 -- I will close the issue manually when I'm confident this is working as expected.

Summary

These changes add a new workflow file (.github/workflows/trigger-website-rebuild.yaml) which runs when the metadata/gorefs.yaml file is changed in the master branch.

It first validates the gorefs.yaml file according to its associated schema. Theoretically any validation issues would have been caught by the qc.yaml workflow during a PR. So this is just sort of a fail-safe against someone ignoring that check or committing directly to master.

If the validation passes we generate an access token using the GO Workflow Bot app installed in this repo. Then we use that token and the GitHub CLI¹ to trigger the deploy.yaml workflow² in the geneontology/geneontology.github.io repo.
