ulauncher: 5.9.0 -> 5.10.0 and patch

[aaronjanse]

Motivation for this change

• updates Ulauncher (ulauncher: 5.9.0 -> 5.10.0 #112540)
• adds patch to explain error when ulauncher is not installed globally (Ulauncher throws an error on launch #119350)

I've bundled these two changes because the latter affects code review.

Is adding clearly-labeled notes to software allowed? If not, what would be a better alternative?

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Ensured that relevant documentation is up to date
• Fits CONTRIBUTING.md.

I don't like the way I patched this package. It feels inappropriate to edit someone else's error message, so I'm closing my own PR

FWIW, that error message would have saved me a bunch of looking stuff up...
