Suggest `std::sync::LazyLock` instead of `once_cell::sync::Lazy`
This PR suggests std::sync::LazyLock instead of once_cell::sync::Lazy.
This issue was discussed three months ago right after the stabilization of std::sync::LazyLock in Rust 1.80,
and since two more minor versions of Rust have been released since then,
I think it's about time.
Many thanks,
Closes #1217
thx!! Do we really want to mention 3rd party crates when the exact same functionality is available in stdlib?
I found this PR (eventually) because clippy now has a pedantic lint against lazy_static: https://rust-lang.github.io/rust-clippy/master/index.html#non_std_lazy_statics
Would be nice to get this landed so it's easy for folks who see that lint to update.
