Add option for same pathname but new hash

[sitch]

Currently, these won't type properly if you wanted the equivalent of href="#some-id"

const id = "some-id"

<Link
  href={`${id}`}
/>

or

<Link
  href={{
    hash: id
  }}
/>

Should just need to union a hash only type:

type Hash = { hash: string }

export interface LinkProps ... {
  // Union `Hash` here
  href: Route | StaticRoute | Query | Hash
  ...
}
