Is your feature request related to a problem? Please describe.
It would be nice if an update to the playbooks was made so that it would support Raspberry Pi (ARM CPU).

Describe the solution you'd like
Just an update to the playbooks should be suitable.

Now that I have a physical Raspberry Pi Model 4's on-hand, I have been able to test the ansible-playbook and can confirm that no updates are required on the repository side. However, additions to Raspberry Pi /boot/cmdline.txt will need to be made per the journal -xeu output because of the cgroups (v2) error.

Documentation to the k3s-ansible repository can be found here
Issue on Rasbian x64 #179

This will be documented and if an agnostic approach can be implemented with ansible I will go that route - else it will just be a note in the set-up for kubernetes.
