Tyarel8 d9d022733f feat(std/help): Add --help for external-commands (#15962) ...

# Description
I have just discovered the `std/help` command and that it can use `man`
or other programs for externals. Coming from windows, I don't have `man`
so what I want is just to run `external_program --help` in most cases.
This pr adds that option, if you set `$env.NU_HELPER = "--help"`, it
will run the command you passed with `--help` added as the last
argument.
