Lints move back and forth from pedantic to non-pedantic all the time, so
whatever is here is definitely out of date and not particularly
meaningful.

This avoids this large block of imports getting rewrapped every time
imports change, which made it hard to see what was being added/removed.

Fix typo

Add syn::punctuated::Pair::punct_mut
