feat(Linux): Automatically build a Flatpak bundle

lmgarret commented 1 week ago

Pull Request Description

This adds the manifest file to build a flatpak bundle with each release. It does not cover publishing to Flathub, which is a different topic IMO.

Heavily inspired by the Jellyfin Media Player flatpak manifest, building ffmpeg, mpv and other dependencies by source as recommended for flatpaks.

It is a potential solution to #53

[X] If a new package was added, did you ensure it works for all supported platforms? Is the package well maintained
[X] Check that any changes are related to the issue at hand.
