Deprecate an `after_bundle` callback in Rails plugin templates

Since fbd1e98cf983572ca9884f17f933ffe92833632a, Rails plugin does not
run `bundle install` when generating.
Therefore, `after_bundle` callback is not actually executed after `bundle`.

Since there is a difference between the name and the actual behavior,
I think that should be remove.
