SPA Overrides tekijä The0x539

This extension gives a very simple popup menu for replacing microfrontends in a single-spa page.
Individual overrides can be disabled without forgetting the configured URL.
This is not a full replacement for "single-spa Inspector" - in particular, it lacks the "inspector" features in favor of sticking to just overrides. In exchange, it hopefully provides a more straightforward UX for doing so.
