Rust Version

Clap Version

clap 4.6.6

Minimal reproducible code

use clap::Command;

fn cli() -> Command {
    Command::new("command_name")
        .subcommand_required(true)
        .subcommand(
            Command::new("test_command")
        )
}

fn main() {
    let _matches = cli().get_matches_from(vec!["command_name", "--hel"]);
}

Steps to reproduce the bug with the above code

Run the reproduction code to get the error output.

Actual Behaviour

The error text suggests that --help requires a <COMMAND>.

error: unexpected argument '--hel' found

  tip: a similar argument exists: '--help'

Usage: command_name --help <COMMAND>

For more information, try '--help'.

Expected Behaviour

The suggestion should not indicate that a command is required.

...
Usage: command_name --help
...

Additional Context

When misspelling an argument with ArgAction::Version or ::Help, for example the default --help argument, the usage text indicates that the argument requires a command (<COMMAND>). It seems that version and help commands don't actually require any command.
