Add usePrompt hook

[PatrickDeVries]

• Prompt a user with a message when they attempt to navigate to a new page unless a condition is met
• If the user accepts, navigate to the original destination
• If user rejects, stay on the current page
• Should be functional for all routing methods using window event listeners

This would be a nice add for sure, though I think a one-size-fits-all solution might be hard to put together.

A window confirm should work universally for routing frameworks that rely solely on the window location and history. Unfortunately, there are SSR specificities to consider, and SPAs by nature avoid conventional routing.

These links should provide a decent starting point. Will update as I find more!
