Action extension that would open a deep link in the app (#423)

* Early version of an action that would open a deeplink in the app

* Extend routeur support + catch deeplinks

* Cleaning extension code, using what local packages has to offer

* Removed useless stuff from the extension

* Added action icon ; Thanks Dall-E for the icon

* Added the action name within a localizable file

* Fix routeur
