fix: show the instant payments when they are the only supported PMs

[longyulongyu]

Summary

Fix the bug that the drop-in is not rendered when there are only instant payments.

Tested scenarios

To reproduce:

• For the manual flow, pass the following to the checkout config

paymentMethodsResponse: {
            paymentMethods: [
                {
                    configuration: {
                        merchantId: '12345678',
                        gatewayMerchantId: 'testMerchant'
                    },
                    name: 'Google Pay',
                    type: 'paywithgoogle'
                }
            ]
        },

• Specify the instantPaymentTypes: ['paywithgoogle'] in the drop-in config
• The drop-in is not rendered
