No instructions for CentOS Stream 8 and 9 and all versions of RHEL

[xuiqzy]

There are no instructions for the successor project of CentOS, CentOS stream. For context, Red Hat Enterprise Linux (RHEL) 9 is based on CentOS Stream 9 and in turn Fedora 34.

Version 8 and 9 are out, version 9 since 2021-12-03 and version 8 since 2019-09-24, but neither version is listed in the instruction dropdown. Installing CentOS Stream 9 is an option for popular vServers like Hetzner Cloud.
Version 8 is still supported before 2024-05-31, so should probably also be added.

Are the instructions just the same as for (old) CentOS 8 and Fedora, so just use the snap?

Another very popular distro that is missing is RHEL, in all versions. Probably also the same instructions with using the snap, at least for half recent versions of RHEL?
