[Bug]: Basename is not respected in loaders and actions redirects

[manzano78]

What version of React Router are you using?

6.4.1

Steps to Reproduce

1. Create a data browser router with some routes and a basename: createBrowserRouter(routes, { basename: '/m' });
2. In any route, attach a loader or an action (both are impacted) which returns or throws (both are impacted) a redirect to another route represented by an absolute path: throw redirect('/some-route');

Expected Behavior

The new browser URL should be https://example.com/m/some-route

Actual Behavior

The new browser URL is https://example.com/some-route. The basename (/m) is missing, so we don't see the expected page as it couldn't match.

Just merged the PR for this, hoping to get a 6.4.3 prerelease out soon (possibly today) and a stable hopefully next week 👍

👋 Just did a prerelease (6.4.3-pre.0) which should fix this if you want to give it a shot!
