Title: Fix the reference to `rbenv shell` and make it `rbenv sh-shell` instead.

A number of my colleagues and I were somewhat perplexed by the recent non-existence of the 'shell' command, only to find that it was now actually 'sh-shell'. This updates the output of `rbenv help` to reflect the change.
