👋 Hello @zeo-rap, thank you for your contribution. Just wanted to let you know there's a failing test. (CI log)

Failure:
PaymentIconTest#test_Every_payment_SVG_meets_accessibility_requirements [/home/runner/work/payment_icons/payment_icons/test/unit/payment_icon_test.rb:99]:
{:message=>"The 'octopus' SVG file should have a 'aria-labelledby' attribute on the root <svg> node"}

👋 Hey @zeo-rap, can we update the icon according to these guidelines? For example should have white background instead of transparent.
