Fix corrected example in E0759.md

This pull request fixes #86061, which was probably caused by a copy-paste error, where the supposedly corrected code example was also marked with `compile_fail`. Thus, the fact that the "correct" example actually _isn't_ correct was not caught by the doc-tests. This pull request removes the incorrect `compile_fail` annotation and fixes the example.

@ -16,13 +16,13 @@ fn bar(x: &i32) -> Box<dyn Debug> { // error!
Add `'static` requirement to fix them:
```compile_fail,E0759
```
# use std::fmt::Debug;
fn foo(x: &i32) -> impl Debug + 'static { // ok!
fn foo(x: &'static i32) -> impl Debug + 'static { // ok!
x
}
fn bar(x: &i32) -> Box<dyn Debug + 'static> { // ok!
fn bar(x: &'static i32) -> Box<dyn Debug + 'static> { // ok!
Box::new(x)
}
```
