Remove the PeerAuthentication exceptions for the gitlab webserive/sidekiq's dependency check initContainer

[Racer159]

Describe what should be investigated or refactored

Currently there are two PeerAuthentication exceptions for the gitlab webserive/sidekiq's dependency check initContainer. This should be removed once UDS Core implements native sidecars.

This is waiting for 1.29+ versions of k8s to get enough traction to implement in UDS Core.
