Auto merge of #83491 - jyn514:remove-pretty, r=pnkfelix
Remove unstable `--pretty` flag It doesn't do anything `--unpretty` doesn't, and due to a bug, also didn't show up in `--help`. I don't think there's any reason to keep it around, I haven't seen anyone using it. Closes https://github.com/rust-lang/rust/issues/36473.
