Refactor: remove statement_descriptor from Stripe Payment Element Gateway

[jonwaldstein]

Resolves: GIVE-1948
Related: #7259

Description

This removes the statement_descriptor from Stripe Payment Element Gateway. This is the result of a Stripe api change to the attribute for card payments. Since Payment Element is dynamic, the safest & simplest option is to remove the attribute and rely on the statement_descriptor set on the account level instead of the request.
