fix(linux): Update launchpad PPA by tier

fix(web): dev_resource compile fix

Update launchpad.sh so that `${tier}` corresponds to the ppa link:
`stable` --> ppa:keymanapp/keyman
others --> ppa:keymanapp/keyman-daily
 ppa depends on the `${tier}`.

When cancelling the Android system notifications about lexical model update being available, the notification would still remain.

This passes the language ID so the dialog can be cancelled.

Fixes #2540
