Description

When a merchant wants to block credit cards on Google Pay, the backend sends allow_credit_cards: false in the /session-tokens response. This PR adds support for this by including the allowCreditCards field in the Google Pay parameters type definition in src/Types/GooglePayType.res
Backend PR : juspay/hyperswitch#11758

How did you test it?

you don't need to add   allowCreditCards: option,  The sdk passes allowed_payment_methods as raw JSON through to the Google Pay API
and arrayJsonToCamelCase transforms the key to allowCreditCards automatically
