Idea: "latest" directory to always hold latest fork

[lightclient]

Just an idea. I always have to search for "shanghai" when coming to the spec, it might be nice to have a directory that is update with each fork called "latest". Downside is if people link to things in it, they could break big time.

We might be able to do this with a custom 404 page and some JavaScript: https://docs.github.com/en/pages/getting-started-with-github-pages/creating-a-custom-404-page-for-your-github-pages-site
