fix(react-router): Simplify types for LoaderFunctionArgs

[LekoArts]

Description

React Router made an internal breaking change in 7.6.1: https://github.com/remix-run/react-router/blob/main/CHANGELOG.md#v761

@react-router/dev - Renamed internal react-router/route-module export to react-router/internal

We were relying on react-router/route-module to give type annotations for rootAuthLoader.

In this PR we're moving away from using unstable internal APIs and instead use the publicly available LoaderFunction/LoaderFunctionArgs for our rootAuthLoader() and getAuth() types.

Previously we were trying to get this type: https://github.com/remix-run/react-router/blob/c06ec85cf05e0ec5a3f399160ae3512206fac980/packages/react-router/lib/types/route-module-annotations.ts#L103-L136

But we can also use https://github.com/remix-run/react-router/blob/c06ec85cf05e0ec5a3f399160ae3512206fac980/packages/react-router/lib/router/utils.ts#L185-L209 because it's the same shape.

Fixes #6012

This was already resolving to any previously, so we can remove the reliance on react-router/route-module here
