verify: Output of `--help` is wonky

[tcharding]

While reviewing #626 I ran verify --help and sow the output describing --quite has ... in it. No clue what I was thinking when I wrote that but it doesn't look that good.

 cargo run -- --help
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.01s
     Running `/home/tobin/~/.cache/cargo/debug/verify --help`
Usage: verify [OPTIONS] <version>

Arguments:
  <version>  Verify specific version of Core (use "all" for all versions)

Options:
  -t, --tests <TEST_OUTPUT>  Optionally check claimed status of tests
  -q, --quiet...             Run tests in quiet mode
  -h, --help                 Print help

And the relevant code in main.rs

    let cmd = Command::new("verify").args([
        arg!([version] "Verify specific version of Core (use \"all\" for all versions)")
            .required(true),
        arg!(-t --tests <TEST_OUTPUT> "Optionally check claimed status of tests").required(false),
        arg!(-q --quiet ... "Run tests in quiet mode").required(false),
    ]);
