The examples for `ControlFlow::is_break` and `ControlFlow::is_continue` still use `#![feature(control_flow_enum)]` despite being stabilized

The title pretty much describes it. It's a minor thing, but I still think it should be addressed. Other stabilized types with a mix of stable and unstable API do not use #![feature()] in in their stable examples.

This was fixed in #94283

Yea, the fix is in the latest master (https://doc.rust-lang.org/nightly/std/ops/enum.ControlFlow.html#method.is_break), but will need to ride the trains to the stable docs.
