✨ add `helm package` hook

[plusiv]

Description

I Added helm package as a hook to package helm charts.

[!NOTE]
I used the helmlint hook as the foundation of a this new hook since it's basically the same logic.

Documentation

As documentation says about helm package command ...

This command packages a chart into a versioned chart archive file. If a path is given, this will look at that path for a chart (which must contain a Chart.yaml file) and then package that directory.
