Bug: in “error scrape” mode, plugin always complains about PHP 5.6

In a nutshell,

if (isset($_GET['action']) and $_GET['action'] == 'error_scrape') {
die('Sorry, AWeber Sign Up Form requires PHP 5.6 or higher. Please deactivate AWeber Sign Up Form.');
}

… this code from aweber.php needs to actually check the PHP version. It pops up on EVERY error_scrape, preventing other plugins from showing their own errors, and obviously complains about a PHP version even if I’m running on 8.1.
