Running example in a separete project, after enabling the API and waiting a minute for propegation, works without any manual quota changes.

N2_CPUs quota in python-docs-samples-tests set at 24

However, noxfile_config.py has these tests running on 3.8, 3.12, and 3.13. It's possible that since the error says Requested 12.0, available 0.0 that each running execution removes 12 CPU from the quota, so you can only run two concurrent dataproc workflows in the same project at the same time.

Solution may be to increase the quota to allow more concurrent tests, or maybe change the tested versions to just 3.9 and 3.13 (current "required" versions)

I've updated the quota to 48, which appears to now allow for more paralell tests.
