[Bug]: Basename is case sensitive

[dhulme]

What version of React Router are you using?

6.0.0-beta.2

Steps to Reproduce

Create a basic router with a basename like below (or https://codesandbox.io/s/practical-waterfall-g9770?file=/src/App.js)

export default function App() {
  return (
    <BrowserRouter>
      <Routes basename="/app">
        <Route path="/" element={<h1>Home page</h1>} />
      </Routes>
    </BrowserRouter>
  );
}

Visit /APP

Expected Behavior

/ route renders because basename matches (ignoring case), as mentioned in #4866

Actual Behavior

/ route does not render

@mjackson Perhaps it makes sense to include a caseSensitive prop on Routes that applies to the basename, perhaps it sets the default for all nested routes as well. Thoughts?

[mjackson]

I think we just always assume basename is not case sensitive for now. We can add a caseSensitive prop later if someone really needs it.

Fixed in #8000
