Fixed stripe-php not fully php7.4 compliant

[Xon]

Affected version

2.1.9

XenForo itself doesn't trigger this bug, but the stripe-php bundled with XenForo 2.1.x, will error if toArray() is called on the StripeObject

ErrorException: [E_NOTICE] Trying to access array offset on value of type int src/vendor/stripe/stripe-php/lib/Util/Util.php:45
#0 src/vendor/stripe/stripe-php/lib/Util/Util.php(45): XF::handlePhpError(8, '[E_NOTICE] Tryi...', '/var/www/html/...', 45, Array)

We were a few versions behind where we should be. Should be fixed for the next release. Thanks.
