Disable Route Normalizer

This simple module is intended to be used on a multilingual site using redirect module when you need to have a language neutral content page without any redirection to a path prefix, which means there will not be any preferential language shown in the URL.

The functionality provided is available by default on clean Drupal installation but not when using redirect.
The module doesn't have any configuration and it creates a custom route for every language neutral content types, appling a "_disable_route_normalizer" to skip redirect.

Note that this modules doesn't include or override Language Negotiation Rules, which means that the negotiated language will be used for the interface.
