[Rancher2] Single Node Using Docker fails with cgroups v2

[dgiebert]

Request Summary:

It seems to be a known issue that the single node docker install does not work on operating systems using the newer cgroups v2. Therefore I would suggest adding a section to the installation page warning about that fact and pointing the users to a k3s + helm setup.

Maybe similar to how its done here: https://rancher.com/docs/rancher/v2.6/en/backups/restoring-rancher/#known-issues

Details:

• Documentation Link

Hi, I found this doc bug but I also have the prerequisite fix when using cgroupv2, which kernel module to enable and more we also fix the entrypoint rancher container
