The original directions were writen specifically for Rocky8 SIG-CLOUD
kernel updates with the assumption that everyone reading would know
about the different branches depending on the major version they were
using. We now explicitly call them out.
There was also an assumption that the reader was well familiar with
setting up a dev environment to do backporting from a src.rpm but that
is not always the case so included those directions.
Also linked to how to onboard to Rocky Account Services so that anyone
can be linked back on how to contribute.
