`CreateUserServicePassword` type documentation incorrect

[KeithGillette]

Bug report

Describe the bug

The MongoServicePassword.createUser API documentation:

1. Lists CreateUserServicePassword as the type for each of that method's parameter properties but the API documentation does not define CreateUserServicePassword, which I believe is the type of the parameter itself.
2. Includes no Description for the parameter properties, leaving me clueless as to what a cleanUser is.

To Reproduce

Read the referenced documentation.

Expected behavior

The documentation should be accurate, complete, and understandable.

@pradel this is as simple as making password optional in CreateUserServicePassword, right?

I can submit a PR to fix this when I have some time this weekend.
