ci: give the unit job the setup headroom its own startup guard requires

check_workflow_startup_safety rejects a job whose deadline can preempt pytest: setup can
take 35 minutes plus 5 of runner overhead, so a 20 minute pytest budget needs the job
capped at 60, not 55. Three entries in the unit matrix still sat at 55 and failed the
guard on every pull request, including on litellm_internal_staging itself

Raising those three to 60 matches the ten entries already at that value and turns the
code-quality job green. This is unrelated to the rest of the branch, kept as its own
commit so it can be dropped or cherry-picked independently
