helm_resource: version

[kplimack]

• adds ability to provide --version argument to helm_resource

[nicks]

i think people usually do this as helm_resource(..., flags=['--version=...'])

[jplimack]

@nicks perhaps, but something more declarative is easier to consume and understand the behavior of; hence me not knowing of this way to provide this argument

[nicks]

I would be fine with a note on the readme on how to set --version. there's already a note about --set where you can put it.

I don't think we want to replicate every helm install flag as starlark arguments

i added some notes to the README and test on how to use --version https://github.com/tilt-dev/tilt-extensions/tree/master/helm_resource#helm_resource
