Patch bug in React Router 6.3
This is a backport of React Router PR #9300 to React Router 6.3 which is the version pinned in Remix.
This fix allows non-alphanumeric characters to start a route path. This means
/.well-known/ or even
/😍 will work.
Currently this only patches the development build as the production files are minified. I will update the patch once I setup to build React Router locally.
