[Failing Test]: beam_PostRelease_Python_Candidate script broken

[Abacn]

What happened?

test: https://ci-beam.apache.org/job/beam_PostRelease_Python_Candidate/

This test suite is documented as part of release candidate validation. From the history the last successful run was V2.46.0 rc1; and as of V2.49.0 rc1 it is broken. Error message:

18:53:26 ERROR: Failed to create topic [projects/apache-beam-testing/topics/wordstream-python-topic-1]: Resource already exists in the project (resource=wordstream-python-topic-1).
18:54:02 ERROR: (gcloud.pubsub.topics.create) Failed to create the following: [wordstream-python-topic-1].

This is kind of minor, but maybe we can clarify what this suite actually does and name it better.

I only see 2.46.0 and 2.49.0 runs. Is it not actually in use and the instructions are wrong?

Changed to P2 since we now understand the cause well (not due to Beam).

It is referred in release documentation as part of release validation:

1. Create a PR to trigger Python validation job, including

checking the history this step has long been existed.

Validation may be done with this automated process or run manually. Since 2.46.0 passed the validation, the issue seems to be more recent (delete then create topic with same name failing).

Nevertheless I think a proper fix to the script should be avoiding create topic with same name twice. Leave this issue open for this task.
