heroku: 3.43.12 -> 3.43.16

[peterhoeg]

Motivation for this change

This is the last version of the deprecated client but using the latest CLI.

We also lose the broken fhs wrapper script because the CLI is now compiled instead of just downloading the binary.

Fixes: #15262 and #20752

Things done

• Tested using sandboxing
  (nix.useSandbox on NixOS,
  or option build-use-sandbox in nix.conf
  on non-NixOS)
• Built on platform(s)
  • NixOS
  • macOS
  • Linux
• Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Fits CONTRIBUTING.md.

/usr/bin/env: ‘ruby’: No such file or directory

Adding ruby to binPath helps, but now:

rasen@Larry ~/nixpkgs> ./result/bin/heroku 
 ▸    dashboard is not a heroku command.
 ▸    Perhaps you meant whoami?
 ▸    Run heroku _ to run heroku whoami.
 ▸    Run heroku help for a list of available commands.

(though, all other commands work fine.)

I have ruby in my global path, so maybe that's why it runs here without it. I have just added it in and running ./result/bin/heroku --help (and the other subcommands) work fine although I do get the peculiar message, when run without any arguments.

[rasendubi]

Works fine. (except when run without subcommand.)
