Switch kuberenetes_tests to run with uv run (apache#42836)

This is a no-op change right now, but as part of the provider re-org in apache#42505
this sets us up to be able to load the providers code in the tests

The reason this change is done separately is that changes to breeze code form
forks doesn't take effect, and this small change makes it easier to land on
main without having to re-create that large PR.
