title: React router v6 doesn't support <Prompt /> or usePrompt
body: <p>Migrating a codebase to react-router v6 specifically <code>v6.2.1</code> and running into some issues when trying to use <code>&lt;Prompt /&gt;</code> component or <code>usePrompt</code>, turns out they are not available in this version of react-router. Or am I wrong? If anyone have run in to the same issue or if you know a way around this issue, your help would be appreciated.</p>
