To Reproduce

1. Deploy a HelmRelease via FluxCD (as an OCI container in my case)
2. Observe

Helm upgrade failed for release github-actions-system/gha-runner-scale-set-controller with chart [email protected]+b4e577166191: failed to create resource: Deployment.apps "gha-runner-scale-set-controller-gha-rs-controller" is invalid: spec.template.labels: Invalid value: "0.9.3+b4e577166191": 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 'my_value',  or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?')

### Describe the bug

This is a case of the chart using `.Chart.Version` as a label, directly. Since SemVer supports `+`, this can result [in invalid Kubernetes labels](https://helm.sh/docs/chart_best_practices/conventions/#version-numbers).

### Describe the expected behavior

The labels [here](https://github.com/actions/actions-runner-controller/blob/master/charts/gha-runner-scale-set-controller/templates/deployment.yaml#L28) need to be properly escaped.

In other places of the chart, this is done already, by replacing `+` with `_`, e.g here [[1](https://github.com/actions/actions-runner-controller/blob/master/charts/gha-runner-scale-set-controller/templates/deployment.yaml#L7)], [[2](https://github.com/actions/actions-runner-controller/blob/master/charts/gha-runner-scale-set-controller/templates/_helpers.tpl#L35-L37)].
