:nocov: Transforms values of a hash using the given block

@yield [Object] block to transform each value @return [Hash] new hash with transformed values @return [Enumerator] if no block given @note This will be run in CI on Ruby 2.3, but we only collect coverage from current Ruby

Rails <= 5.2 had a transform_values method, which was added to Ruby in version 2.4.
This method is a backport of that original Rails method for Ruby 2.2 and 2.3.
