docs: remove the useUnifiedTopology option from the MongoDB examples
Browse files Browse the repository at this point in the history 
The `useUnifiedTopology` option is now deprecated and using it throws
an error with TypeScript.

Reference: https://www.mongodb.com/docs/drivers/node/current/whats-new/#what-s-new-in-4.0

> It is no longer required to specify `useUnifiedTopology` or `useNewUrlParser`.
