Update tooling to better understand Textfield types

[snowystinger]

🙋 Feature Request

We updated our types to better choose between textarea and input in useTextfield. Our documentation can't quite handle it. We need to update our docs to more clearly display our types.

🤔 Expected Behavior

For example, useTextField<T = DefaultElementType> should be useTextField<T = 'input'>

As per discussion: it maybe enough to remove DefaultElementType and replace with 'input'
