fix GHA workflow timeout-minutes 4320

[casperdcl]

there are quite a few workflows with hardcoded timeout-minutes: 4320. Said workflows are broken due to #1067.

Also users who notice the warning and upgrade to timeout-minutes: 50400 will still see an annoyingly persistent warning.

As per #1067 (comment) we should:

• increase visibility or automate a fix
  • minimum (easy): throw an error instead of logging a warning
  • ideally (more involved): parse the workflow file and set GH_5_MIN_TIMEOUT accordingly
• better logging
  • https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#setting-an-error-message and/or https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#adding-a-job-summary, etc.

potentially need to repurpose for general restart mechanism issues?
