What problem does the feature solve?

If "url" strategy is set and a user opens the url with baseLocale, the middleware should redirects the user to url without locale. For example:

1. baseLocale is set to "en"
2. A user opens url "http://localhost:5173/en"
3. middleware redirect to "http://localhost:5173" because "en" is a base locale

The same use case should be applied when locale in url doesn't exist.

What does the proposed API look like?

This feature should be enabled by default.
