connect-api-examples/connect-examples/v2/php_payment requires php 8.0.0 (should be 7.1)

[verticon]

1. Clone connect-api-examples locally
2. Open terminal at connect-api-examples/connect-examples/v2/php_payment
3. run "composer install"
4. Examine vendor/composer/platform_check.php and find the following:
   if (!(PHP_VERSION_ID >= 80000)) {
   $issues[] = 'Your Composer dependencies require a PHP version ">= 8.0.0". You are running ' . PHP_VERSION . '.';
   }

Huh? README says 7.1 or greater

If I run php_payment on php 8.0.8 all is good. PHP 7.4.21 results in the php version check failing.

Looks like ramsey/uuid is the culprit
