* add language to gh page

* display language on page

* fixes

* log for debugging

* rename some providers for consistency on naming conventions.

- fix key name, use classname from content. defaults to filename.
- fix provider display name, use name from content. defaults to filename.
- only build from animeproviders and movieproviders path. prevents unnecessary objects populating json file.
