Fix up kernel srpmproc directions

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.

+#### Build Local Git Tree: Remotes
+If you're doing novel development here you can skip this step.  However most people are going to be cherry-picking patches from Linus's Mainline at Kernel.org, or another remote, so you'll need to add them here to preform the cherry-picks.
+
+Example is just fro adding the Linus kernel.org mainline.

-As of 2024.01.29 `srpmproc` cannot work off dev branches so this code will need to be on the main `r<version>` branch.  Once this is done re-running `srpmproc` using the above script or exact same command parameters used when creating the local `srpmproc` will use the new local HEAD.

+`srpmproc` will only refernce code that is actually in the git repo, a little contrary to how traditional development works.
+This requires that both the large monolithic patch and the `directives.cfg` file changes need to be commited for `srpmproc` to actually pick them up.
