Description of problem:

In ROSA HCP wizard in multiregion side, user has initiated cluster installation without executing the  oidc operator role command. This leads to a situation where the cluster installation will be paused for users action post installation initiation.  Unfortunately there is no login command that indicated to user that user needs to be logged to regionalized endpoint before the operator role creation. We need to include those command definition as part of "action required" dialog 

Steps to Reproduce:

1. Open OCM UI staging using https://console.dev.redhat.com/openshift/?multiregion=true 
2. Open ROSA wizard and launch Hosted flow.
3. Select region as "ap-southeast-1" region and proceed to next steps.
4. Reach to cluster roles and polices step.
5. Select oidc configs and define prefix definition . Do not execute any commands.
6. Initiate the cluster installation.
7. See the "Action required" dialog definition in installation step.

Actual results:

In Step 6,  the command reference doesn't indicate that you need to login to regionalized url prior to the  create action for oidc operator roles from "Action required" dialog.

Expected results:

Add rosa login command  with reference to regionalized api from "Action required" dialog
