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.
