App can be packaged from distribution for Linux

[nang-dev]

This is how we package the app: https://github.com/trypear/pearai-app/blob/main/CONTRIBUTING.md#packaging

and for distribution instructions: https://docs.google.com/document/d/1hZahz2UNrtZOgHZkquqNO7Jfoe0Pd0OA7Ud16ts_AKs/edit?usp=sharing (Mac so far)

we need to some extra stuff to distribute to linux users i think
