+Fix bug with `resolveTo` in splat routes
+
+- This is a follow up to [#10983](https://github.com/remix-run/react-router/pull/10983) to handle the few other code paths using `getPathContributingMatches`
+- This removes the `UNSAFE_getPathContributingMatches` export from `@remix-run/router` since we no longer need this in the `react-router`/`react-router-dom` layers
