Fix tidy check if book submodule is not checked out

This fixes tidy in a checkout without submodules. https://github.com/rust-lang/rust/pull/127786 added a new cargo workspace, and the corresponding checks in tidy. There is code in tidy to skip those checks if the submodule is checked out, but that code assumed the root of the workspace was also the root of the submodule. With `rustbook`, the root is `src/tools/rustbook`, but the submodules it needs are in the `src/doc` directory.

The solution here is to explicitly list which submodules are needed instead of assuming the root is also the submodule.
