values-arm64.yaml: nodeselector is 'arm' instead of 'arm64'

[campaquino]

As the value was changed to 'arm', but 'arm64' is reported by k8s as architecture, no applicable node for deployment can be found by k8s.

Expected Behaviour

Openfaas can be deployed on 64bit arm machines like RPi4

Current Behaviour

K8s reports it couldn't find any suitable node ('0/1 nodes are available: 1 node(s) didn't match node selector.')

Possible Solution

Revert the change from 'arm64' to 'arm', made in values-arm64.yaml at the nodeSelector beta.kubernetes.io/arch

Steps to Reproduce (for bugs)

1. setup arm64 machine (e.g. RPi4) with appropriate OS and K8s (e.g. k3sup install --ip --user )
2. setup openfaas by 'arkade install openfaas' or the equivalent helm command line
3. wait until helm/arkade has finished its work
4. check k8s for status of deployments

Context

I tried to setup Openfaas on my RPi4 using Ubuntu and k3s. For convenience k3sup and arkade were used.
Unfortunately it did not start any container of the helm chart on my RPi.
