Fix #9728 - cron.php fails with "must be compatible" error

[kgaillot]

… from AOPInboundEmail.php

Description

Trying to run cron.php with PHP 8 fails with a fatal error (see issue salesagility/SuiteCRM-Core#143):

PHP Fatal error:  Declaration of AOPInboundEmail::handleCreateCase(Email $email, $userId) must be compatible with InboundEmail::handleCreateCase($email, $userId)

Motivation and Context

This allows cron.php to succeed on a system with PHP 8.

The fix was suggested by pgr on forum team: "it’s a known issue that was aggravated in PHP 8 because it used to be a warning, now it’s FATAL"

How To Test This

Run cron.php with PHP 8

(Note: for the script to fully succeed, PR salesagility/SuiteCRM#9731 for Issue salesagility/SuiteCRM#9730 must also be applied)
