React Router: Potential CSRF via PUT/PATCH/DELETE document requests

Certain CSRF checks in React Router v7 Framework Mode were insufficient and run on POST requests, but were bypassed on PUT/PATCH/DELETE requests. This is a low severity vulnerability because modern browser protections CORS preflight, SameSite cookies already block the cross-origin attack vectors...
