Rollup merge of #61965 - phil-opp:patch-4, r=scottmcm

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.
