Rollup merge of rust-lang#133530 - timvisee:master, r=jhpratt

Use consistent wording in docs, use is zero instead of is 0

In documentation, wording of _"`rhs` is zero"_ and _"`rhs` is 0"_ is intermixed. This is especially visible [here](https://doc.rust-lang.org/std/primitive.usize.html#method.div_ceil).

This changes all occurrences to _"`rhs` is zero"_ for better readability.
