Pagination support for all resources

It'd be nice to have a single [pagination implementation](https://developer.wordpress.org/rest-api/using-the-rest-api/pagination/) for all resources. What do you all think?

```swift
let users = wordPressApi.paginate(User.self, orderBy: \.name)
let firstPage: [User] = try await users.nextPage()
let secondPage: [User] = try await users.nextPage()

// Same syntax can be used on Post
let posts = wordPressApi.paginate(Post.self, orderBy: \.modifiedDate)
let firstPage: [User] = try await posts.nextPage()
let secondPage: [User] = try await posts.nextPage()
```
