User reports that attempts to use 'serverTrustStoreConfigMapName' are failing.  A ConfigMap is produced, but changes to the CheCluster CR do not 'remain' after the change is made.  The server does not restart, no action seems to be taken.

Could we please document:
1)  The procedure to add a CA to truststores

2) The location of the truststores that should be updated.  (This will help with debugging/validating if the procedure works.)

So, reviewing the current doc [2], we find section 5.4, "Adding custom public SSL certificates to CodeReady Workspaces trust-store".  Could we please enhance this:

• To ensure it works as described
• Revise so it explicitly covers all use cases.  We have a section for "If CodeReady Workspaces is deployed using Operators", but confusingly nothing else
• Please list the location of the affected truststores, so the change can be validated
