[Tool] Output help on 'flutter pub' (#126211)

This change makes `flutter pub` show the help usage:

```
PS > flutter pub
Commands for managing Flutter packages.

Global options:
-h, --help                  Print this usage information.
-v, --verbose               Noisy logging, including all shell commands executed.
                            If used with "--help", shows hidden options. If used with "flutter
                            doctor", shows additional diagnostic information. (Use "-vv" to force
                            verbose logging in those cases.)
-d, --device-id             Target device id or name (prefixes allowed).
    --version               Reports the version of this tool.
    --suppress-analytics    Suppress analytics reporting for the current CLI invocation.
    --disable-telemetry     Disable telemetry reporting when this command runs.
