[book] Old version of the book gets mixed up with new version -> style on <code> elements makes them impossible to read

Google sent me to this link for the libAFL tutorial: https://aflplus.plus/libafl-book/baby_fuzzer.html

Which currently looks like this on my machine (Chrome 145.0.7632.160, macOS):

At first I thought this was a humorous stylistic choice for the introductory paragraph, but it's present through the entire page. A bit of investigation shows that there's two versions of the book kinda mashed together under `https://aflplus.plus/libafl-book/`. The newer version (https://aflplus.plus/libafl-book/baby_fuzzer/baby_fuzzer.html) looks correct.

I'm not sure exactly what the build pipeline looks like for that site, but it might be good to clean up older HTML before generating the new HTML. Or set up some redirects for traffic inbound from search engines.
