Need support for local fonts to satisfy EU GDPR

[grexe]

In the EU, it is actually illegal as per GDPR to make a web site reach out to hosted fonts without user consent.
This is why people serve fonts locally, as a static asset.
However, astro config does not support that and strictly expects a CDN path.

So, something like this will fail:

	fonts: [
		{
			provider: "local",
			name: "Inter",
			cssVariable: "--font-sans",
			src: [
				{ path: "./public/fonts/InterVariable.woff2", style: "normal" }
			],
			fallbacks: ["sans-serif"],
		},

yielding a parser error:

[config] Astro found issue(s) with your configuration:
! Invalid FontProvider object
! Unrecognized key: "src"

This forces me to use CSS directly.
Supporting this would be great, but maybe it's an Astro limitation?

Hey. Astro's font handling is specifically designed to be privacy-preserving and GDPR-friendly. Even if you specify a provider like Google, the font is downloaded at build time and self-hosted, so the user never loads anything from a third party server. More info in the Astro fonts guide
