7341: Fix warnings when running `cargo doc --document-private-items` r=Veykril a=jyn514

These were the warnings previously:

This does *not* fix the following warning, because it is actually rust
code and rustdoc is being over eager:

```
warning: Rust code block is empty
  --> crates/parser/src/grammar.rs:16:5
   |
16 |   //! ```
   |  _____^
17 | | //! // test function_with_zero_parameters
18 | | //! // fn foo() {}
19 | | //! ```
   | |_______^
   |
help: mark blocks that do not contain Rust code as text
   |
16 | //! ```text
   |     ^^^^^^^
```

https://github.com/rust-lang/rust/pull/79816 should make this
configurable so the warning can be `allow`ed.
