The `helm init` command fails under releases of Helm prior to 2.17.0
due to the fact that the stable charts have been moved[1].
Helm 2 is EOL and ideally this should be bumped to Helm 3 at some point,
but that is a bigger exercise that will require notifying all users
so this minor bump should improve overall UX without affecting users.

The init command was removed from helm with v3, no initialization is
needed anymore. So only run the init task if the version is <= 2.
