charts: drop chart version from resource labels

[fgiudici]

Fixes #846

This is part of the recommended labels: https://helm.sh/docs/chart_best_practices/labels/#standard-labels

It's fine to drop it for me if it breaks the marketplace, but I wonder why that is the case.
Also other marketplace charts use the same label, do they all have the same issue?

The issue is that Rancher chart versioning is in the form: 1.0.#+upX.Y.Z (charts version docs).
This is not a syntax allowed for Kubernetes Labels (the '+' character) 🤦🏼
For the other charts in the marketplace, yes, all have the same issue too... just checked, some hardcode the value to something else, others remove the "+" from the label's value... not sure at that point having something different than the chart real version makes sense 🤷🏼
