Authorize()'s refreshToken expiry

## Issue

Hi, I've read the documentation for authorization function of this library (https://commerce.nearform.com/open-source/react-native-app-auth/docs/usage/authorization).
The response contains the expiration only for the accessToken and not for the refreshToken. Can you tell how much time does the refreshToken has before it expires as well?

I am asking because currently I am in a situation that I need the refreshToken from authorize(config) to be used on refresh() like the next code snippet for my Azure Active Directory login.

`// Refresh token`
`const refreshedState = await refresh(config, {
refreshToken: authState.refreshToken,
});`

But the problem is, when I use the `authState.refreshToken` when the `authState.accessToken` from authorize(config) has expired, refresh(config) fails. But as long as the `authState.accessToken` is not yet expired, the refresh(config) call returns a successful response.

I'm thinking if the `authState.refreshToken` is being expired the same time as `authState.accessToken`. Because refresh(config) fails only when the `authState.accessToken` has expired.
