✨ (go/v4) Add scaffold for e2e webhook checks

A new scaffold marker is introduced to automatically adds end-to-end tests for webhooks in the test/e2e/test.go

The scaffolded tests include:
- Validation that cert-manager has successfully provisioned the secret, when/if an webhook is scaffold for the project.
- Verification that the CA bundle is injected into the mutating webhooks, if a mutating webhook is scaffolded.
- Verification that the CA bundle is injected into the validating webhooks, if a validating webhook is scaffolded.
