[Bug]: Passing Location objects into createMemoryRouter's initialEntries doesn't type-check

[ShaneDrury]

What version of React Router are you using?

6.4.2

Steps to Reproduce

• Use a Partial<Location> object in initialEntries when creating a memory router:

import { createMemoryRouter } from 'react-router-dom';
const router = createMemoryRouter([], {
  initialEntries: [{ pathname: '/foo', state: { myState: 'bar' } }],
});

Expected Behavior

The code type-checks and works as normal, where the state is accessible in the components with useLocation.

Actual Behavior

The code does not type-check but works as normal, where the state is accessible in the components with useLocation.
The type error is:

TS2322: Type '{ pathname: string; state: { myState: string; }; }' is not assignable to type 'string'.

This seems to be because initialEntries of createMemoryRouter is typed as string[] rather than InitialEntry[] which is what createMemoryHistory uses and initialEntries is passed on to.

The documentation also seems to show the type as InitialEntry[].

Thanks! Just merged a fix for this in #9498, should be out in a 6.4.3-pre.1 hopefully today and then a stable 6.4.3 later this week or next
