https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/db/mssql_odbc
mentions that, quote:

Do not forget to install the Microsoft ODBC driver on the Zabbix server or the Zabbix proxy.
See Microsoft documentation for instructions: https://docs.microsoft.com/en-us/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server?view=sql-server-ver15

while official documentation mentions FreeTDS only:
https://www.zabbix.com/documentation/5.4/manual/config/items/itemtypes/odbc_checks/unixodbc_mssql

This mismatch confuses zabbix users. Would be nice to resolve this "inconsistency" someway. Maybe mention both drivers shortly on both resources, as alternatives.
