Rollup merge of #79858 - sasurau4:doc/update-unstable-book-const-fn, r=oli-obk
Update const-fn doc in unstable-book
Fix #79691
I couldn't find suitable examples. It seems that `const_fn` feature-gate used only following place. https://github.com/rust-lang/rust/blob/810324d1f31eb8d75e8f0044df720652986ef133/compiler/rustc_ast_passes/src/feature_gate.rs#L560-L562
And example like following emits [E0379](https://doc.rust-lang.org/error-index.html#E0379).
```rust
#![feature(const_fn)]
trait Foo {
const fn bar() -> Self;
}
```
Any other suitable example exists, please let me know.
