Re-export `Element` type from `domhandler`

[demurgos]

Hello,
I am migrating a project from cheerio@1.0.0-rc.12 using types "@types/cheerio" @0.22.35 to cheerio@1.0.0.

An issue that I hit is that I am not able to name the type returned by the cheerio $ function: the return type is Cheerio<Element>, but the Element type comes from the domhandler which is not exported.

A workaround would be to add the domhandler lib as a direct dependency of my project, but this brittle as it relies on manually keeping both the direct dependency on domhandler and the one from cheerio in sync. As domhandler types are exposed in the public API of Cheerio, they should be re-exported to ensure reliable usage.

Element is the most prominent example, but all public types should be reachable from the cheerio package. Other examples are AnyNode, Document, or ParentNode.
