Even though the default value of innodb_purge_threads is 4 in MySQL 5.7 or later, some of the documentation says "The default value is 1".

How to repeat:
Open the following pages.

* https://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_purge_threads
* https://dev.mysql.com/doc/refman/8.0/en/innodb-parameters.html#sysvar_innodb_purge_threads

The content of tables are correct, but the descriptions are incorrect.
