Lichess-Links shouldbe redirected to the app

## Description
Opening a Lichess-link (https://lichess.org/...) should be redirected to be opened in the app.

**Solution:** very simple - just a quick change in the android manifest

Start by locating the Android manifest and review its current intent-filter declarations. Update the manifest so links matching https://lichess.org/... open in the app, then verify that a Lichess link is handled by the app rather than the browser.
