Hello preact team!

Recently, we ran into some TypeScript issues in a project where we use preact with styled-components.

Looking a bit more in depth at the issues, they seemed to stem from a few missing types from @types/react, this PR aims to add those types in.

With those changes, we got a project with preact+styled-components working correctly (PS: this is a good first sign, but the project isn't that huge, so there could be things that don't work in 100% of the situations)

It would likely fix this issue

VNode seemed to be the closest thing in preact to ReactElement from what I could gather, but this might be wrong.

Seems right, VNode looks to cover all the same properties (and a couple more).

Here I mixed the @types/react implementation with preact's one for ComponentProps.
I think this makes sense, but I have some doubts, so would be great if someone with more understanding of the preact side can confirm 👼
