man pages are out of date

[ehuss]

Someone on IRC noticed that the cargo man pages are a little out of date or wrong. In particular, cargo-bench documents a --release flag that does not exist. Browsing through some of the other entries I see a few that are also out of date. It might be worthwhile to review all of them and bring them up-to-date.

Note: I'm preferring to wait and see what the wg-cli group comes up with. They have a prototype that will generate man pages from the CLI help, so maybe we'll be able to use that.

Here's the upstream (clap) issue for auto-generating man pages: clap-rs/clap#552
