fix: oci chart rendering version

[buroa]

This fixes a simple issue where upon rendering the chart with OCI manifests adds a +sha to it. This results in a failure to install because it's not a valid kubernetes label with the + in it.

Other charts replace the + with a _ and that seems to be the standard fix.

actions-runner-controller    0.10.1+9f0f5cfb9a0e    False        False    Helm install failed for release actions-runner-system/actions-runner-controller with chart gha-runner-scale-set-controller@0.10.1+9f0f5cfb9a0e: 1 error occurred:
