User sees less-readable error message directly from Stripe/StripeSCA backlog

[filipefurtad0]

Description

Failing authentication in Stripe SCA displays an informative but less readable/user friendly error message - in this case a long message, text with underscores (see pic below).

Expected Behavior

An informative but user-friendly message should be shown.

Something like this, perhaps:
"The provided Payment Method has failed authentication. Please try again with valid credentials or choose another payment method.

Actual Behaviour

The error message reads:
"The provided PaymentMethod has failed authentication. You can provide payment_method_data or a new PaymentMethod to attempt to fulfill this PaymentIntent again."

Steps to Reproduce

1. Place an item in the cart
   2.- set up/choose Stripe SCA as a payment method
2. attempt to place an order using a card like 4000 0027 6000 3184, and fail authentication, when asked to.
3. The error message should appear.

Possible Fix

Yea we just had a client that is stuck and didn't understand the error message. In other languages than English, it is very difficult to understand as it mixes class/variables names in English and the other language..
