Migration guide for Version 4.x.x

• The themeColor, textColor, and cursorColor properties have been removed from CreditCardForm due to changes in how it detects and applies application themes. Please check out the example app to learn how to apply those using Theme.
• The cardNumberDecoration, expiryDateDecoration, cvvCodeDecoration, and cardHolderDecoration properties are moved to the newly added InputDecoration class that also has textStyle properties for all the textFields of the CreditCardForm.
