Wrong stabilization version for `std::matches!` since v1.86

Location

std::matches! in v1.85: https://doc.rust-lang.org/1.85.0/std/macro.matches.html
std::matches! in v1.86: https://doc.rust-lang.org/1.86.0/std/macro.matches.html
std::matches! in nightly: https://doc.rust-lang.org/nightly/std/macro.matches.html

Summary

The matches! macro was stabilized in v1.42, but later versions of Rust instead report the stabilization version as v1.0

This seems to have regressed due to #135352. cc @notriddle
