Update mysql connect parameter

Hello there, 

I really like patator and just ran into the issue when trying to bruteforce `mysql_logins`, that the following error occurred: 
```
<class 'TypeError'> 'passwd' is an invalid keyword argument for connect()
```

I checked the mysqlclient repo (stated in your dependency list) -> there it is written that `passwd` is deprecated (https://github.com/PyMySQL/mysqlclient/blob/main/MySQLdb/connections.py#L65).

However in this line https://github.com/PyMySQL/mysqlclient/blob/main/MySQLdb/connections.py#L154 they are still setting it. 

If I change the parameter in your script from `passwd` to `password` it works accordingly. 

I hope this helps - keep the work up. 

Cheerz,
