ingress labels not compatible with RKE2-style kubernetes versio

[stephanbertl]

There is an issue with the ingress template of datalore located at https://github.com/JetBrains/datalore-configs/blob/1069a97e1006a2a4da45f66277c0ded0834c89f9/charts/datalore/templates/ingress.yaml#L21C1-L22C1

ver: {{ .Capabilities.KubeVersion.GitVersion }}

When using Rancher Kubernetes with RKE2, the version of Kubernetes is:

"v1.25.13+rke2r1"

Using that value, helm cannot create the ingress because

Error: INSTALLATION FAILED: 1 error occurred:

• Ingress.extensions "datalore" is invalid: metadata.labels: Invalid value: "v1.25.13+rke2r1": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue', or 'myvalue', or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9.]*)?[A-Za-z0-9])?')

@stephanbertl thank you, I've deleted the label
