[Bug]: ValidatesContainer suite needs attention

[tvalentyn]

What happened?

Two issues:

1. Sometimes a suite times out after 15 min: https://ci-beam.apache.org/job/beam_PostCommit_Py_ValCont/

2. We need to update gcloud on jenkins for this test to pass on Python 3.10.

We have an image and updated the worker #9, I'll try to update the rest.
