AppImage packaging (#439)

* AppImage packaging

* Add flags to specify location of required local files

`--build=path` specifies where on the system is the directory with pre-build game binaries (must have binaries `isle` and `isle-config` in `path/bin` and game-specific libraries in `path/lib`)
`--apprun=path` specifies where the apprun is
`--desktop-file=path` same for the desktop file

* Move to packaging/linux

* Move building to appimage/build and ignore it in git

* Use local icon. Option to specify location for it

* Cleaning

* Attempt at Github automation

* Update CMakeLists.txt

* Fix build

* I guess it doesn't need quotes

* Update CMakeLists.txt

* Update release.yml

* Work around for liblego1.so loading, fix arguments

* Create testing.yml

* Update testing.yml

* I should pay more attention to what docs say

* Fix copy-pasting mistake

* Add AppImage packaging to the Release workflow

* Try fixing filepicker

* Delete testing.yml

* Fix releases

Can't specify where linuxdeploy leaves the file without specifying the name of the file, which I don't want to do, so just move the file in `dist` after packaging.

* Remove unnecessary changes

* Add qt6-xdgdesktopportal-platformtheme as deps

Needed to call the xdg filepicker, basically desktop-specific filepicker. Hopefully this will allow to use it in AppImage

* Get back flatpak in release

* Update release.yml

* Remove libglew-dev from apt install

* Fix duplicate upload artifact

* Update release.yml
