feat: add e2e test for naming conventions enforcement

[nbendafi-yseop]

Add e2e to test that permitted-key-name prevents ExternalSecret from accessing keys if regex doesn't match key's path

  CRD
    ✓ ensure CRD is managed correctly
    ✓ should reject invalid ExternalSecret manifests

  secretsmanager
    ✓ should pull existing secret from secretsmanager and create a secret with its values (2247ms)                                                                   
    ✓ should pull TLS secret from secretsmanager (134ms)
    permitted annotation
      assuming role
        ✓ should not pull from secretsmanager (3435ms)
      enforcing naming convention
        ✓ should not pull from secretsmanager (3427ms)

  ssm
    ✓ should pull existing secret from ssm and create a secret from it (130ms)
    permitted annotation
      ✓ should not pull from ssm (3427ms)


  8 passing (13s)

PS: should not pull from secretsmanager test is just nested under assuming role describe, while its content is unchanged, by this PR

This PR needs #411 for tests to pass
