Subject: [PATCH] hare: unstable-2023-10-23 -> unstable-2023-11-27

And also:
- move platform and arch to outer let-in
- patch tzdata paths to use the nix store
- set `outputs` to `[ "out" "man" ]`
- append `nixpkgs` `hare version`'s output
- compact `postFixup` phase
- rework description
- move `binutils-unwrapped` only to `buildInputs`
