chore(finance): update mastercard patterns and test

[matthewmayer]

See
#2350 (comment)

Updates the mastercard patterns to remove the weird 677189... pattern
which is identified as a unionpay card, and instead add the much more
common patterns starting 2221 – 2720 which were introduced in 2017
https://www.cardfellow.com/blog/new-mastercard-bins/

Following this change, all mastercard card numbers pass validator's
isCreditCard
check, so switch to using that instead of a custom regex
