* Ignore doctest for non-exported macro

Rust 1.62 introduced a breaking change where doctests for non-exported
macros are now run by default. These don't compile because the macro
can't be imported in it.
See https://github.com/rust-lang/rust/issues/97030

 for more info.

* Run cargo fmt

* Use $crate instead of crate in macro
