Perhaps I missed something, but it seems solid-meta doesn't currently expose a way to set json-ld on the head.

JSON-LD is Google's preferred schema markup and it's kind of a big deal for SEO.

I am currently trying out Solid Start and couldn't find a way to set it up, I was expecting we could do something like:

<Script type="application/ld+json">{"json linked data goes here as a string"}</Script>

Anyway, I am about to open a PR that would allow us to do:

<JSONLD>{{ key: "value", ... }}</JSONLD>

which, IMO, would be even more ergonomic.

I don't like the fact that JSONLD is all caps. Maybe we can find a better name.
