Show why a job is waiting for a resource and the resource_group when in `WAITING_FOR_RESOURCE` status

Problem

As a DevOps Engineering troubleshooting a long running pipeline, I want to see more data quickly about the resource group a job is waiting on, so I can efficiently fix the problem and get developers working again.

Proposal

Show some information on the job detail page when in this status about the resource group the job is waiting for and link to a page with details of the resource group (if available).
