Description:
Manual for binary log and replication *-do-db filters has the wrong syntax for multiple-table updates examples.

How to repeat:
Open https://dev.mysql.com/doc/refman/8.0/en/replication-options-binary-log.html#option_mysqld_... or https://dev.mysql.com/doc/refman/8.0/en/replication-options-replica.html#option_mysqld_rep..., then check multiple-table updates examples:

mysql> UPDATE db1.table1 SET col1 = 10, db2.table2 SET col2 = 20;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET col2 = 20' at line 1

Correct syntax:

mysql> UPDATE db1.table1, db2.table2 SET col1 = 10, col2 = 20;

or

mysql> UPDATE db1.table1, db2.table2 SET db1.table1.col1 = 10, db2.table2.col2 = 20;

Suggested fix:
Fix examples.
