[CI] bicep lint job in CI fails randomly and does not spark joy

https://github.com/Azure/azure-dev/actions/runs/30320139612/job/90154113914?pr=9282

In PRs where I'm not touching any bicep, I'll see bicep lint fail. It's possible it's failed in other pipeline runs/commits, but it seems to be some transient network issues.

This is a "do a quick peek and see if there's a quick fix/retry loop" type issue. I don't think we need to get deep into how bicep pulls deps.

Start with the linked GitHub Actions run and the CI workflow that invokes the Bicep lint job. Check whether the failure is transient and whether a retry is appropriate; done means unrelated pull requests no longer fail randomly because of this lint step.
