Preact type definitions + potentially other frameworks

[itsMapleLeaf]

As of writing, only definitions are included for React. As a framework-agnostic solution, should probably add broader support.

Not sure if there are any others we should include as well, like Inferno, or Vue JSX? I feel like the usage numbers aren't high enough to justify this; gotta draw the line somewhere. But if someone contributes them, I won't say no 🤷‍♂️

Typescript uses the JSX namespace that is usually provided by those libraries. Maybe have an internal minimal JSX namespace type which would only support the additional props.

Like here (https://github.com/tw-in-js/use-twind-with/blob/main/packages/preact/index.ts#L17) but using the JSX namespace.
