Auto merge of #133533 - BoxyUwU:bump-boostrap, r=jieyouxu,Mark-Simulacrum

Bump boostrap compiler to new beta

Currently failing due to something about the const stability checks and `panic!`. I'm not sure why though since I wasn't able to see any PRs merged in the past few days that would result in a `cfg(bootstrap)` that shouldn't be removed. cc `@RalfJung` #131349
