Avoid missing docs warning on pub extern crate

Due to rust-lang/rust#112308, the public re-export of the pac will trigger a missing docs warning in rust 1.71.0. This is bogus, as the doc string would not be shown in the rendered docs anyway. However, the warning would be annoying, so add a short doc string to the item.
