redhat/configs: Disable CONFIG_RT_GROUP_SCHED in rhel config
Fedora and rhel-rt config already have CONFIG_RT_GROUP_SCHED disabled.
RT_GROUP_SCHED does not play well with cgroups v2. Rather than keep
this enabled, disable it in rhel going forward.
This is tied to Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1980362
