Remove mentions of removed `offset_to` method from `align_offset` docs

The `offset_to` method was deleted in https://github.com/rust-lang/rust/pull/52814.

The replacement for the removed method is `wrapping_offset_from`. However, neither method takes an `usize` as argument, so I don't think that it makes sense to mention them.
