Mostly removes unnecessary use of `extraPkgs = pkgs: appimageTools.defaultFhsEnvArgs.multiPkgs pkgs;`
This caused some packages to be listed twice.
Also, fix some styling, and accidental use of top-level packages (sometimes due to the `with;` keyword, e.g. on `beeper`).
Remove inclusions of `bash`, since `bashInteractive` is already present by default.
`appimageTools.wrapType2` no longer creates a binary `$out/bin/${name}` if `pname` and `version` is provided.
Derivations that have worked around this behavior with a `mv $out/bin/{${name},${pname}}` broke as a result.
This should fix most instances.
contex: #271071
they're unnecessary since https://github.com/NixOS/nixpkgs/pull/161739/files
which links the schemas to their correct fhs locations and adds
gsettings-desktop-schemas and hicolor-icon-theme to appimage fhs
The upgrade apparently made it necessary to also add `XDG_DATA_DIRS`
to fix the crash mentioned in the added comment.
I copied this solution from:
`pkgs/applications/misc/devdocs-desktop/default.nix`
