sysutils/py-kubernetes: Update 33.1.0 => 34.1.0

Changelog:
https://github.com/kubernetes-client/python/blob/v34.1.0/CHANGELOG.md

• Remove python version requirement as it doesn't make sense since we have minimum python-3.10 in ports tree
• Remove security/py-oauthlib dependency just like upstream did. It's installed by www/py-requests-oauthlib anyway.
