Fix --help in clap

This functionality was broken by "f38363d - Switch to 2021 edition of
Rust", or more specifically with the change to resolver = 2.

The `--help` flag requires a feature in clap to be enabled, which is either a newly introduced requirement, or the feature(s) were somehow included implicitly when using resolver = 1.
