Fix: GetAllAvailableResources Filtering by Resource Path

Fix EmbeddedResources.GetAllAvailableResources to respect the specified resource path when enumerating embedded resources.

Previously, resources were filtered only by file extension. Adding locale-named JSON files under anywhere else caused them to be included when querying Assets/Locales, resulting in duplicate entries in the language menu.
