Fix false positive with missing_docs and #[test]

[ogoffart]

Since #130025, the compiler don't ignore missing_docs when compiling the tests. But there is now a false positive warning for every #[test]

For example, this code

//! Crate docs
#![warn(missing_docs)]
#[test]
fn just_a_test() {}

Would emit this warning when running cargo test

warning: missing documentation for a constant
 --> src/lib.rs:5:1
  |
4 | #[test]
  | ------- in this procedural macro expansion
5 | fn just_a_test() {}
  | ^^^^^^^^^^^^^^^^^^^

Fixes #130216

[ogoffart]

Alternative would be to add #[doc(hidden)] instead for the generated const

Edit: I went for this option.

Could you also change the #[allow(missing_docs)] on the test harness main function to #[doc(hidden)] which should fix #130218 as well, and also change the test to use forbid/-F.
