feat(mobile): add biometric plugin (#829)
* chore: update deps, make mobile script paths relative * feat(biometric): setup plugin folder * feat: implement iOS * add api * android * fix plugin name * also check empty info.plist entry * add example * fix android * supress * lint * better explanation * add partners & contributed by * change ext * license headers * update vite * add covector setup * tauri/dox removed * add example * docs --------- Co-authored-by: Lucas Nogueira <lucas@tauri.app>
