Feedback on Swap Space and Kernel Swappiness | RHEL8 Known Issue

Browser environment: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36

CONTEXT:
Per this Red Hat Solution Documentation (https://access.redhat.com/solutions/6785021), they acknowledged that for the RHEL8 OS, updating the vm.swappiness parameter does not set the intended swappiness setting system wide to all cgroups.
They released a new parameter, vm.force_cgroup_v2_swappiness, that needs to be set to 1 to allow for the intended vm.swappiness value to be set system wide.

Since a vm.swappiness of 1 is recommended for Couchbase installs, users on RHEL8 OS aren't receiving the intended benefit and will suffer from High Swap Usage which can lead to memory issues.

Refer to this Slack thread for additional background: https://couchbase.slack.com/archives/C06ABNRG2SV/p1721168333461989

REQUEST:
Add a note to the respective doc page that acknowledges the specific swappiness customization needed in RHEL8 to benefit from the correct configuration for a Couchbase install.
