Description of problem:
The downstream docs ** for ** installing the orchestrator plugin with RHDH 1.7 are missing some steps that appear in the upstream docs.

In the upstream docs for installing the orchestrator plugin with RHDH 1.7, it is required to not only add the orchestrator plugins in a configmap, but also to add a secret, another configmap, and also edit the backstage resource to point to the added secret and CM (see list of resources to be added here 

These steps are missing from the downstream docs and should be added. If they are omitted, there are errors in the orchestrator UI about a missing token.

Steps to Reproduce

1. Deploy RHDH operator 1.7.0
2. Follow the downstream docs for deploying orchestrator with the RHDH operator (see linked docs above).

Actual results:
Errors in the orchestrator UI due to missing tokens. After adding the missing config, the errors resolved.

Expected results:
Upstream and downstream docs should match.
