Pass page props to application wrapper

[shivjm]

I wanted to add a footer whose content changes based on the current route, but the application wrapper is only passed the component. This PR adds the PageProps under a new page property. I’m a bit confused about whether this is the right approach, though.

render currently sets props per the docs and declares it as Record<string, unknown> to pass safely to h. Passing those props alongside Component works and passes type checking, but I’m not sure whether there’s a reason for the unknown or not, so I can’t tell whether I’ve broken something. (And I can’t run the tests because it keeps failing on account of the port being in use. No idea why. I’m on Windows, and I can see it succeeds in CI.)

Looks like a slightly more generic version of #599. I have a similar use case, so I'd love for something like this to get accepted.

Closing in favour of #1229. Either way, thank you @shivjm 🙏🏾

Yup, that sounds good. I’m glad someone was able to implement it in a better way.
