Add flag package-with-index

[IGx89]

Hello! chart-releaser v1.6 added flag --package-with-index: helm/chart-releaser#304. Once #146 gets merged would you be able to add that flag to this action as well?

Thanks!

Hello not sure if this has been raised before but when I use the packages_with_index: true values it still packages it and stores it as a release instead of with the index.yaml file in the gh-pages branch

@or4dx there hasn't been a release sadly since this functionality was added to the action -- still waiting for it. I'm seeing recent changes in this repo however so maybe a release is coming soon?

[IGx89]

@or4dx they just released v1.6 it looks! Give that a try.

Closing since this is now added (thanks!), although I haven't been able to use it myself yet due to an unrelated regression (#171).
