.cr-index folder must be manually created

[ralgozino]

Hello!

Maybe I'm doing something wrong here, but I needed to manually create the .cr-index folder for the cr index command to work.

This is what I did:

$ docker run --rm --entrypoint=sh -it -v $PWD:/app quay.io/helmpack/chart-releaser:v1.4.0
/app # cr package chart
Successfully packaged chart in /app/chart and saved it to: .cr-release-packages/gatekeeper-policy-manager-0.2.0.tgz
/app # cr index --owner sighupio --git-repo gatekeeper-policy-manager
