As part of https://issues.redhat.com/browse/CFE-811, we added a featuregate "RouteExternalCertificate" to release the feature as TP, and all the code implementations were behind this gate.

However, it seems https://github.com/openshift/api/pull/1731 inadvertently duplicated "ExternalRouteCertificate" as "RouteExternalCertificate".

   $ oc get featuregates.config.openshift.io cluster -oyaml 
<......>
spec:
  featureSet: TechPreviewNoUpgrade
status:
  featureGates:
    enabled:
    - name: ExternalRouteCertificate
    - name: RouteExternalCertificate
<......>     

    Both RouteExternalCertificate and ExternalRouteCertificate were added in the API

We should have only one featuregate "RouteExternalCertificate" and the same should be displayed in https://docs.openshift.com/container-platform/4.16/nodes/clusters/nodes-cluster-enabling-features.html
