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
### Motivation for this change
Long time waiting for the update. Took the matter into own hands.
### Things done
Incremented the version number to the latest stable release.
Changed the sha512 value.
Opened the application and used it for a while.
PS: This is my very first contribution ever. I hope this fullfills the requirements.
