Stop publishing Python packages from main branch pushes

[acsoto]

What type of PR is this?

/kind bug

What this PR does / why we need it:

Stop publishing the Python CLI and Python SDK to PyPI on every push to main.

PyPI package versions are immutable, so triggering package publishes from regular main branch changes causes repeated failures when the package version has not been bumped. This change limits Python package publishing to release tags and manual dispatches, which matches the expected release flow more closely and avoids noisy deployment failures.

Which issue(s) this PR fixes:
Fixes #

Special notes for your reviewer:

This is a stopgap change only. It does not define the long-term Python package versioning or release policy yet.

Does this PR introduce a user-facing change?:

NONE
