useAuthenticatedFetch - doc block comment is inaccurate

[shyleo]

Issue summary

The comment in useAuthenticatedFetch seems to be inaccurate:

shopify-frontend-template-react/hooks/useAuthenticatedFetch.js

Lines 5 to 17 in 1e92031

	/**
	* A hook that returns an auth-aware fetch function.
	* @desc The returned fetch function that matches the browser's fetch API
	* See: https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API
	* It will provide the following functionality:
	*
	* 1. Add a `X-Shopify-Access-Token` header to the request.
	* 2. Check response for `X-Shopify-API-Request-Failure-Reauthorize` header.
	* 3. Redirect the user to the reauthorization URL if the header is present.
	*
	* @returns {Function} fetch function
	*/
	export function useAuthenticatedFetch() {

This header is not added, and indeed it should not be - the Access Token should be added on the backend, not from the frontend, if I'm reading Shopify docs correctly. This OAuth tutorial explicitly says that this header is added on the backend, and the App Bridge tutorial says that authenticatedFetch is supposed to add the Session Token under the Authorization header.

Expected behavior

The comment should be rewritten to explain what the function actually does:

1. It adds an Authorization header to the request, with the value Bearer <Session Token Here>

Actual behavior

Inaccurate comment
