### What does this PR try to resolve?

This PR fixes some broken markdown in doc comments.

### How should we test and review this PR?

1. Navigate to the online docs and observe broken markdown:
    * https://doc.rust-lang.org/nightly/nightly-rustc/cargo/index.html
    * https://doc.rust-lang.org/nightly/nightly-rustc/cargo/core/compiler/struct.TargetInfo.html#structfield.crate_types
    * https://doc.rust-lang.org/nightly/nightly-rustc/cargo/sources/registry/struct.RegistryConfig.html#structfield.dl
    * https://doc.rust-lang.org/nightly/nightly-rustc/cargo/sources/registry/fn.max_unpack_size.html
2. Run `cargo doc --document-private-items --open` and verify that the broken markdown has been fixed.

### Additional information

The broken inline code was found by a [new rustdoc lint](rust-lang/rust#105848) and these changes will be required to deny the lint in the rust-lang/rust repository.
