_content/doc: use mysql.NewConfig() instead of mysql.Config{}

[methane]

The zero values for mysql.Config is not good for default.

See https://pkg.go.dev/github.com/go-sql-driver/mysql#Config

If a new Config is created instead of being parsed from a DSN string, the NewConfig function should be used, which sets default values.
