Add advanced install instructions for RHEL 8
What does this Merge Request do?
Investigating FIPS compliance for GitLab, I had occasion to set up the GDK on an RHEL 8 machine. This is a paid product with similarities to CentOS, but the repositories do provide some aid that isn't available in CentOS, as far as I can tell, so I think it warrants its own segment.
I plan to add documentation to the GitLab repository that details how to get a FIPS-enabled development environment set up so we can pursue / vet FIPS-compliance changes. One of those steps is to install GDK on a RHEL8 machine, as I did, so this section will be very useful for that.
