Documentation regarding fractionalSeconds is broken #26

On the page https://docs.operaton.org/docs/documentation/user-guide/process-engine/database/mysql-configuration#jdbc-driver-configuration there is a link to the MySQL documentation, which is no longer valid.

https://dev.mysql.com/doc/connector-j/8.0/en/connector-j-connp-props-datetime-types-processing.html#cj-conn-prop_sendFractionalSeconds

While searching for the correct page to share, I saw that MySQL acted on their side, so before just chaning it, I will do some research on the matter, maybe the whole documentation block is obsolete
