Hey @damccorm, I think this PR would solve this issue #35920 (comment). It turned out that ML tests run also in that workflow beam_PreCommit_Python_Coverage so we need to add the filtering for tests that require_docker_in_docker i.e Milvus tests

The tests beam_PreCommit_Python_Coverage running on ubuntu-latest variant exits with code value 5 which indicates no tests to run. This due to the fact (as yet) Milvus dependencies not added properly (existing follow-up PR #35920) so the tests with pytest marker require_docker_in_docker are skipped

SKIPPED [1] apache_beam/ml/rag/enrichment/milvus_search_it_test.py:72: unittest.case.SkipTest: Milvus dependencies not installed: No module named 'pymilvus'

Removing now the ubuntu-latest from beam_PreCommit_Python_Coverage since we're gonna add it later in this PR #35816

Instead of including python_version, could we include the os? That way the generated job names will be different per job

Added OS label to workflow (job_name and test results). Perhaps we can leave the python_version since this workflow currently runs on the default python version which is 3.9 in future potentially this can run on multiple python versions?
