[GRAPHQL] query checkoutSessionDetails doesn't adhere to GraphQl best practices

[dimitriBouteille]

As proposed in this issue (#1218), the objective of this MR is to improve the query checkoutSessionDetails so that it complies with graphQl standards.

• In order not to break the applications with the old query, I made a new query: checkoutSessionDetailsV2,
• The query checkoutSessionDetails is deprecated.
• I also add an exception if no Amazon session is found.

query CheckoutSessionDetails($amazonSessionId: String!) {
    checkoutSessionDetailsV2(amazonSessionId: $amazonSessionId) {
        payment
        shipping {
            city
            firstname
            lastname
            street
            company
            telephone
            region
            region_id
            region_code
            email
            postcode
        }
        billing {
            city
            firstname
            lastname
            street
            company
            telephone
            region
            region_id
            region_code
            email
        }
    }
}
