Path searching for type has incorrect regex

The code at https://github.com/ember-learn/ember-cli-addon-docs/blob/master/addon/routes/docs/api/item.js#L21 is looking for a type to use when looking for a matching module. However when I have a path that has a directory ending in "s", it fails to find the correct module because the type is incorrect.

Given the path "components/yeti-table/header/filters/column/input" the type on the line above will be "components/yeti-table/header/filter" when it should be "component". If you use the regex /^(.*?)s\// it will find the correct type

Looks like this was introduced with https://github.com/ember-learn/ember-cli-addon-docs/pull/167

It seems pretty straightforward and I would submit a pull request, except looking at the tests I have no idea where I would supply a test for this. It looks like you might have to create an addon that had component ending in "s" with sub components somewhere in your test apps.

Comienza en addon/routes/docs/api/item.js en la línea 21 y sigue cómo se deriva el tipo para components/yeti-table/header/filters/column/input. Reproduce el tipo incorrecto y añade después una prueba de regresión que use una ruta de componente que contenga un directorio terminado en “s” y verifica que se encuentre el módulo correspondiente.
