chore: replace nodeSelector with nodeAffinity in chart + manifests

Some K8s distributions might label control-plane nodes with
```
node-role.kubernetes.io/control-plane: "true"
```
rather than
```
node-role.kubernetes.io/control-plane: ""
```
which makes the default `nodeSelector` fail. Replacing it with a `affinity.nodeAffinity` nodeSelector fixes it.
