What does this PR try to resolve?

part of #11408

  • Show --help if there is no man page for the subcommand
  • Do not suggest cargo help config until we add a man page.

How should we test and review this PR?

  1. build cargo
  2. try cargo help config
➜  cargo git:(master) ✗ ./target/debug/cargo help config
Inspect configuration values

Usage: cargo config [OPTIONS] <COMMAND>

Commands:
  get  

Options:
  -v, --verbose...          Use verbose output (-vv very verbose/build.rs output)
      --color <WHEN>        Coloring: auto, always, never
      --frozen              Require Cargo.lock and cache are up to date
      --locked              Require Cargo.lock is up to date
      --offline             Run without accessing the network
      --config <KEY=VALUE>  Override a configuration value
  -Z <FLAG>                 Unstable (nightly-only) flags to Cargo, see 'cargo -Z help' for details
  -h, --help                Print help information

Additional information

I am not sure I should add a test for it because I think we will add a man page for config.
