Replace or document ignored doctests (#11040)
# Objective

There are a lot of doctests that are `ignore`d for no documented reason.
And that should be fixed.

## Solution

I searched the bevy repo with the regex ` ```[a-z,]*ignore ` in order to
find all `ignore`d doctests. For each one of the `ignore`d doctests, I
did the following steps:
1. Attempt to remove the `ignored` attribute while still passing the
test. I did this by adding hidden dummy structs and imports.
2. If step 1 doesn't work, attempt to replace the `ignored` attribute
with the `no_run` attribute while still passing the test.
3. If step 2 doesn't work, keep the `ignored` attribute but add
documentation for why the `ignored` attribute was added.

//! This module contains unit structs that should be used inside `quote!` and `spanned_quote!`
//! using the variable interpolation syntax in place of their equivalent structs and traits
//! present in `std`.
//!
//! To create hygienic proc macros, all the names must be its fully qualified form. These
//! unit structs help us to not specify the fully qualified name every single time.
//!
//! # Example
//! Instead of writing this:
//! ```
//! # use quote::quote;
//! quote!(
//! fn get_id() -> Option<i32> {
//! Some(0)
//! }
//! );
//! ```
//! Or this:
//! ```
//! # use quote::quote;
//! quote!(
//! fn get_id() -> ::core::option::Option<i32> {
//! ::core::option::Option::Some(0)
//! }
//! );
//! ```
//! We should write this:
//! ```
//! use bevy_macro_utils::fq_std::FQOption;
//! # use quote::quote;
//!
//! quote!(
//! fn get_id() -> #FQOption<i32> {
//! #FQOption::Some(0)
//! }
//! );
//! ```
