[PATCH] UBUNTU: [Config][focal/linux-riscv] Turn off CONFIG_RT_GROUP_SCHED

BugLink: https://bugs.launchpad.net/bugs/1875665

We enabled this option for some docker features, but it is
causing reports of regressions. Some more digging on this option
reveals that it's fairly specialized and likely requires
workload-specific configuration and tuning to be of much use, so
turn it back off.
