Fix: Reduce Unauthenticated GitHub Access to Avoid Rate Limit Issue

brew.yaml was commonly hitting a GitHub rate limit by doing
unauthenticated GitHub access.

We have reduced unauthenticated access in brew.yaml in two ways:
  1/ For brew install and test phases, we are providing an access
  token to brew via the HOMEBREW_GITHUB_API_TOKEN environment
  variable. We use a fine-grained personal access token restricted to
  a single repository and with all permissions left on "No Access".
and
  2/ For brew audit, we cannot use the access token described above -
  since the brew audit objects to it. So we have simply eliminated
  doing a brew audit from the workflow.

Taken together, these measures seem to be enough to avoid the rate
limit issue.

homebrew/runformula.sh: Added the "--auditonly" option (but this is
not used in the workflow).
