Docs: Extend exemplary usage

[ohlr]

Although quite trivial afterwards, it took me quite a while to figure out how to use this library with react-helmet.
You might consider updating the docs if not, feel free to close this.

const script = [
    {
        type: "application/ld+json",
        innerHTML: `${JSON.stringify(p)}`,
    },
];
<Helmet script={script} />

Thanks for the suggestion! Documenting Helmet usage is a good idea. If you would like to contribute something here, I'm happy to review it!

I can whip something up otherwise

I'll add some docs here, but I actually think this is a good candidate for google/react-schemaorg, which wraps this library with convenience React-specific functions.

Helmet's innerHTML can be dangerous, e.g. a string can contain '</script>', and that library takes care of serializing/escaping the JSON-LD per the standard.

Oh wow! I did not know there was a react wrapper...
Maybe this is something to mention in the docs

[Eyas]

Yeah, I'll do that soon. The standard <JsonLd> react wrapper doesn't work with Helmet, because Helmet is pretty picky about what child elements it can have. A few people have asked about this before, so getting this done once and for all would be helpful here.
