WHAT
Once customer facing documentation for STS has been published, we should update the addon parameter to point to this doc rather than to the general ROSA install documentation

HOW

• Update https://gitlab.cee.redhat.com/service/managed-tenants/-/blob/main/addons/rhoams/metadata/stage/addon.yaml#L4 to point to RHOAM STS install docs
  • Point of contact in docs team would be joaedwar@redhat.com

TESTS

• Addon points to RHOAM STS install docs

DONE

• Stage, internal and production points to RHOAM STS install docs
