Description of problem:

In docs.redhat.com RHACM documentation a hyper link:

• Managing credentials

is redirecting to a invalid blank page. 

https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.12/html/clusters/cluster_mce_overview 

Version-Release number of selected component (if applicable):

How reproducible:

Always

Steps to Reproduce:

1. Open RHACM documentation
2. Chapter 1 >> Information >> Important 
3. Click on Managing Credential 

Actual results:

404: Page not found

The page you're trying to find was either removed, moved, or maybe the URL isn't quite right.

Expected results:

https://github.com/stolostron/rhacm-docs/blob/2.12_stage/clusters/credentials/credential_intro.adoc#credentials 

It should redirect to a correct documentation link:

https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.12/html/clusters/cluster_mce_overview#credentials
