[legacy-framework] Fix return types of useParam and useParams

[flybayer]

What are the changes and their implications?

The return type of useParam and useParams did not include <type> | undefined which is a bug. Because with Next.js pre-rendering, params can indeed be undefined, and so users must account for this.
