Incorrect behavior with mdbook serve compared to published version.

[andriyDev]

Using mdbook serve locally (following the instructions in the README) is quite different from the version on https://google.github.io/comprehensive-rust.

1. There's no theme or search button.
2. Clicking on a lesson (e.g., Control Flow Basics > break and continue) does not "expand" the appropriate section in the side bar.
3. Links don't "reset" correctly. For example, viewing Control Flow Basics > break and continue, then clicking Tuples and Arrays in the sidebar results in a Document not found page (it is trying to access localhost:3000/control-flow-basics/tuples-and-arrays.html).

This was on Chrome. I also tried it on Firefox (with no extensions) to the same end result. I am serving from a Linux laptop.

I've seen this as well, and assumed it was something I'd done wrong. This started with #2547 but that was reverted in #2564. I assume it has to do with conflicting versions of various mdbook-* packages installed locally, compared to those expected by the repo contents.

How do I know which versions are the right ones? I ran the --locked commands in the README, so I'd assume it should install the same versions as in this repo? (perhaps that's wrong)

Ah looks like downgrading mdbook to 0.4.37 (to match the Github Workflow) seems to have worked. All the features now work correctly.

Should we include this in the README instructions? I might need to report this to mdbook-svgbob or something as well...
