Documentation still references 'deprecated' rustwasm info

I believe this was shortly mentioned under https://github.com/wasm-bindgen/wasm-bindgen/issues/4547, but some pages in the guide/examples page (https://wasm-bindgen.github.io/wasm-bindgen) still have links to the rustwasm guides.

One example is the Introduction section linking to the Game of Life Tutorial. Although I believe the tutorial content is valid, one of the first setup instructions points you to install wasm-pack under the old link, which is no longer available.

I believe ideally either the game of life tutorial (and maybe other guides) should be migrated to a wasm-bindgen project, the old project should be updated to point to valid links (which I guess is hard given it's archived), or old pages URLs like the wasm-pack one should redirect to the newer ones (but I believe this would also require un-archiving the project...).
