[MIRROR] Adds Skill Tracker app for tablets [MDB IGNORE] (#9897)

* Adds Skill Tracker app for tablets (#63013)

Adds a skill tracker app for tablets.

I allowed all tablets to install it, but it is currently not pre-installed by default.

It is only available to tablets, with the conceptual compromise that it requires no extra hardware components, but uses sensors through your hands or something.
