Problem with transactionInfo.totalPrice vs totalPriceStatus=NOT_CURRENTLY_KNOWN

[dostiguyLII]

In the React google-pay-button, by definition, the transactionInfo.totalPrice is required. If we remove it, it won't compile.

However it should be optional, like documented, when transactionInfo.totalPriceStatus = NOT_CURRENTLY_KNOWN.
If we leave it there in the code (otherwise not compiling) then at runtime we get the following error

"DEVELOPER_ERROR in loadPaymentData: PaymentDataRequest.transactionInfo.totalPrice should not be set for totalPriceStatus = NOT_CURRENTLY_KNOWN!"

totalPrice is now mandatory and we removed totalPriceStatus = NOT_CURRENTLY_KNOWN from our dev docs.
