Remove extra space that breaks kubectl YAML block formatting

[philippebi]

With the current ConfigMap template version, the data block format rendered by kubectl is broken after an RKE2 deployment:

> kubectl get cm rke2-coredns-rke2-coredns -n kube-system -o yaml
apiVersion: v1
data:
  Corefile: ".:53 {\n    errors \n    health  {\n        lameduck 5s\n    }\n    ready
    \n    kubernetes   cluster.local  cluster.local in-addr.arpa ip6.arpa {\n        pods
    insecure\n        fallthrough in-addr.arpa ip6.arpa\n        ttl 30\n    }\n    prometheus
    \  0.0.0.0:9153\n    forward   . /etc/resolv.conf\n    cache   30\n    loop \n
    \   reload \n    loadbalance \n}"
kind: ConfigMap
...

It seems that an extra space added during the last commit breaks the rendering.
Removing this extra space restores the correct block format.

> kubectl get cm rke2-coredns-rke2-coredns -n kube-system -o yaml
apiVersion: v1
data:
  Corefile: |-
    .:53 {
        errors
        health {
            lameduck 5s
        }
        ready
        kubernetes  cluster.local cluster.local in-addr.arpa ip6.arpa {
            pods insecure
            fallthrough in-addr.arpa ip6.arpa
            ttl 30
        }
        prometheus 0.0.0.0:9153
        forward . /etc/resolv.conf
        cache 30
        loop
        reload
        loadbalance
    }
kind: ConfigMap
...

I'm confused why you want to make a change to this to allow people to edit it more easily. If this is generated by a Helm chart you SHOULD NOT be editing it directly, as the changes will be lost next time the chart is updated. Don't edit things managed by Helm.

As discussed on Slack this only affects how the configmap string value is displayed in kubectl, the actual contents of the corefile are fine.

Please bump the package version when changing the generated changes without bumping the chart version.
