Match deployment requires PHP 7.4

Trying to run Match with PHP 7.3 resulted in "Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 7.4.0". You are running 7.3.33. in /srv/comanage-match/app/vendor/composer/platform_check.php on line 24"

The requirement should be at this time that PHP 7.2 is required.

Benn has suggested that one of the dependencies is requiring PHP >=7.4.0.

This ticket is to sort it out before releasing Match 1.0.0.
