feat(routes.tsx): add redirect from root to /flows to improve user experience

In this commit, a redirect from the root path ("/") to the "/flows" path was added in the routes.tsx file. This change was made to improve the user experience by automatically redirecting users to the "/flows" page when they visit the root URL. The redirect is implemented using the useNavigate hook from the react-router-dom library.
