SecretKeyRef for kubeconfig doesn't actually have `key`

[kferrone]

I have a generated kubeconfig in a secret and it decided to call the key kubeconfig. FluxCD Helm Controller expects the key to be values.yaml or values.

Here is the kubeConfig secret ref I made:

apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
spec:
  kubeConfig:
    secretRef:
      name: some-staging

Here is the status on HelmRelease when I just ref the secret by name.

KubeConfig secret 'clusters/some-staging' does not contain a 'value' or 'value.yaml' key with data

Here is the error I get from kubectl when I add key to the ref like this:

  kubeConfig:
    secretRef:
      name: some-staging
      key: kubeconfig

error: error validating "out.yaml": error validating data: ValidationError(HelmRelease.spec.kubeConfig.secretRef): unknown field "key" in io.fluxcd.toolkit.helm.v2beta1.HelmRelease.spec.kubeConfig.secretRef; if you choose to ignore these errors, turn validation off with --validate=false

I found the docs that say I can here: https://fluxcd.io/docs/components/helm/api/#helm.toolkit.fluxcd.io/v2beta1.KubeConfig

Which directs me to here: https://pkg.go.dev/github.com/fluxcd/pkg/apis/meta#SecretKeyReference

My feature request is simply to expose the key field on the kubeconfig reference.
