test(batchrelease): add regression for deployment pod-template-hash l…

[Nazihbenbrahim]

Ⅰ. Describe what this PR does

Add a regression unit test to ensure BatchRelease does not get stuck in Verifying when a Deployment’s PodTemplate already includes the pod-template-hash (apps.DefaultDeploymentUniqueLabelKey) label.

The new test (TestDeploymentPodTemplateHashLabelPatch) verifies:

• hash with pod-template-hash differs from hash without it
• UpdateRevision computed from the Deployment template matches the ReplicaSet template hash when the label is present
• BatchRelease label patching proceeds (patches 5 pods and sets controller revision hash)

Ⅱ. Does this pull request fix one issue?

Fixes #308

Ⅲ. Special notes for reviews

• Tests run:
  • go test ./pkg/controller/batchrelease/labelpatch -count=1
• This is test-only coverage; the functional fix was merged previously in Fix the issue where the BatchRelease gets stuck in Verifying when the Deployment's PodTemplate already contains pod-template-hash label #307.
