Switch base types from Cloudflare to Edge Runtime

[IanMitchell]

Describe the request

Right now our base TypeScript definitions pull from Cloudflare types instead of Edge Runtime types. There were some issues in Edge Runtime during its early development that prevented us from using it. Now that version 2 is stable, we should look at swapping over.
