Enables specifying units of measurement for Products

What’s new

Adds the ability to specify a product’s unit of measurement using the unit_label parameter in the product_data hash.

Impact

You can now specify the unit_label when you create a Product by adding a line item to a Checkout Session, Payment Link, Payment Intent, or Invoice. You must include the product’s unit of measurement to meet the requirements of card network Level 2/Level 3 programs.
