Upgrade from Zabbix 6.0.4 to version bigger than Zabbix 6.0.10 will fail on Azure Appliance because user on database zabbix_srv@localhost doesn't have enough privileges to his zabbix database. It requires bigger. **

Steps to reproduce:

1. Create VM with installed zabbix 6.0 LTS via Azure Appliance (it will install Zabbix 6.0.4)
2. Prepare to upgrade your Zabbix to latest LTS version. => Login to mysql and put command (according to changes in database from Zabbix 6.0.11):
   "set global log_bin_trust_function_creators = 1;"
3. Upgrade your Zabbix server with commands:
   {}"# systemctl stop zabbix-server"{}
   "# dnf update zabbix-server -y"
   "# systemctl start zabbix-server"

Result:
Zabbix server is not running because zabbix_srv@localhost user doesn't have permission to create trigger on database (see attached logs).

User zabbix_srv@localhost doesn't have correct permission on database:

mysql> show grants for 'zabbix_srv'@'localhost';
+------------------------------------------------------------------------------------------------------------------------+
| Grants for zabbix_srv@localhost                                                                                        |
+------------------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO `zabbix_srv`@`localhost`                                                                         |
| GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, REFERENCES, INDEX, ALTER ON `zabbix`.* TO `zabbix_srv`@`localhost` |
+------------------------------------------------------------------------------------------------------------------------+

Expected:
Database schema upgrade should pass successfuly.

Workaround and possible solution:
Give to zabbix_srv@localhost full privilage to database (as it's provided on [zabbix.com/download(https://www.zabbix.com/download?zabbix=6.0&os_distribution=centos&os_version=9&components=server_frontend_agent&db=mysql&ws=apache) instruction)

"grant all privileges on zabbix.* to zabbix_srv@localhost;"
