Updates SuperTokens dependency version (#25102)

It's a change to the package.json file to update the supertokens-auth-react version. The changes in this version are:
- How supertokens session works in the context of an iframe
- Dependencies of supertokens-auth-react now use a `^`

--------
One more change is to do with how the redirection works in the demo app in case of session expiry or if a user clicks on signout.
