feat: app issues

Type

Issue

It's not possible to understand, from the title, to which app the issue belongs to.

Feature

Add a label to understand which app the issue refers to.

Motivation

Since ReVanced will not only be aimed at YouTube and Music, this feature would be good to keep the issues section more clear.

Additional context

No response

I'll look into this in a couple hours.
