Consider establishing a staging environment for about.gitlab.com
Problem
We don't use a staging environment for about.gitlab.com like one does in the traditional sense. Right now it is primarily used to just test URL redirects (this will change soon once we switch over to Cloudflare).
The lack of a staging environment, that mimics production, was identified as a cause for a recent Handbook outage in the RCA: #7897 (closed)
Expected outcome
Clearly define whether we need a staging environment for about.gitlab.com, and if so how it should be utilized to prevent being a cause for incidents as identified in the mentioned RCA.
Out of scope
Defining how the staging needs to be configured and implementing it will be done in a separate issue once a decision has been made on whether to proceed with it.
