MySQL 8.0 Secure Deployment Guide — fixes

In the above guide on Part 2, the descriptions of some of the [mysqld] options are the wrong way around.

"validate_password.number_count" should have the description of "The minimum number of numeric (digit) characters that validate_password requires passwords to have if the password policy is MEDIUM or stronger."

"validate_password.mixed_case_count" should have the description of "The minimum number of lowercase and uppercase characters that validate_password requires passwords to have if the password policy is MEDIUM or stronger. "

In the above guide in Part 3, it mentions using the command "bin/mysqladmin -u root -p version" to get to the MySQL console but it should be "bin/mysql -u root -p"
