More Decentralized: About bar

The about bar links all currently go to https://archive.org/about/* etc

There is no endpoint on the Archive to get just the content of that page, and since its dynamically generated, the gateway cant easily cache it.

Can't use a relative link to a name e.g. dweb:/arc/archive.org/about because those pages aren't CORS so don't appear to be able to access them from javascript and pass to window.open

Start by locating the about bar and its link-generation code, then inspect how archive.org/about/* URLs are opened and how the gateway handles dynamically generated pages. The issue does not name files, tests, or a decided implementation, so first establish the expected decentralized link behavior and a concrete completion check around CORS and caching.
