Describe the Bug

The lastest release of Starlight doesn't support Astro v4. I was a bit shocked because the v4 launch post mentioned Starlight being used for the Astro docs. Turns out the docs are still on Astro v3 themselves.

I tried updating Astro to v4 and the app still builds and runs, except with a couple of deprecation warnings.
