Too strict assumption when listing GCS artifact service versions

[zshehov]

The assumption made in the list_versions method:

adk-python/src/google/adk/artifacts/gcs_artifact_service.py

Line 193 in 0c40542

_, _, _, _, version = blob.name.split("/")

is that file names don't include "/". This might be a valid assumption, in which case it can be included in the description of the GcsArtifactService implementation.

@seanzhou1023, this doesn’t really address the issue, it just documents it. This PR however #1669 does, can you check it out?
