Svelte 5 Vite Plugin update

[jermspeaks]

Looks like we will have to wait until @astro/svelte is updated to fix this terminal error.

4:27:59 PM [vite-plugin-svelte] You are using Svelte 5.0.5 with vite-plugin-svelte@3. Active Svelte 5 support has moved to vite-plugin-svelte@4.
	To receive bug fixes and new features update your devDependencies to "@sveltejs/vite-plugin-svelte": "^4.0.0-next.6" and install.
	For framework integrations that depend on it, you might have to add an override:
	"overrides": {"@sveltejs/vite-plugin-svelte": "^4.0.0-next.6"}
