replace deprecated money_format() fn to support PHP 7.4
https://www.php.net/manual/en/migration74.deprecated.php indicates that money_format() is deprecated and should be replaced with NumberFormatter functionality. CiviCRM uses it in a couple of places in one file and in some documentation:
$ grep -R money_format ./*
./CRM/Utils/Money.php: // money_format() exists only in certain PHP install (CRM-650)
./CRM/Utils/Money.php: if (is_numeric($amount) and function_exists('money_format')) {
./CRM/Utils/Money.php: $amount = money_format($valueFormat, $amount);
./CRM/Utils/Money.php: // money_format() exists only in certain PHP install (CRM-650)
./CRM/Utils/Money.php: if (is_numeric($amount) && function_exists('money_format')) {
./CRM/Utils/Money.php: $amount = money_format($valueFormat, $amount);
