chore: remove deprecated types from k8s.ts

[cmwylie19]

Description

We had a circular dependency which caused us to move some types from src/lib/k8s.ts to src/lib/types.ts. We marked them as deprecated and published the news in the release notes. Now we need to remove the types from src/lib/k8s.ts

End to End Test: N/A
