Add nodeSelector to values.yaml

[theninj4]

👋 I've added nodeSelector to the values.yaml so I can target specific machines (my k3s cluster is a mix of pi's and NUCs). This is quite a niche feature, so I've left it out of the default values, and I've tested both with and without any values present.

Preview of the changes:

$ helm template my-audiomuse . | grep -A 1 nodeSelector 
      nodeSelector:
        arch: amd64
--
      nodeSelector:
        arch: amd64
--
      nodeSelector:
        arch: amd64
--
      nodeSelector:
        arch: amd64
