chore(astro): Allow Astro 4.0 in peer dependencies (#9683)

Astro 4.0.0 beta is out so let's adjust our peer deps!
I opted for an open max version for now. THere's a risk of this being
problematic with future major versions but I'd argue we'd get support
requests either way. The important part IMO is the lower bound.
