Spelling mistake?

[N4tus]

There seems to be a small spelling mistake in https://github.com/rust-lang/edition-guide/blob/master/src/rust-2021/or-patterns-macro-rules.md.
In the section 'Migration to Rust 2021' $:_pat should probably be $_:pat.

Since this is a spelling mistake as well I'll add another one here in the comments:
In https://github.com/rust-lang/edition-guide/blob/master/src/rust-2021/IntoIterator-for-arrays.md in the last point of the summary it says IntoIterator::into_inter instead of IntoIterator::into_iter as u/76g2maesu8mk2 pointed out on reddit.
