style: update old mongodb nodejs driver documentation urls

[hasezoey]

Summary

This PR updates old mongodb driver urls to be consistently referring to the 4.9 documentation at https://mongodb.github.io/node-mongodb-native/4.9/modules.html

also updated some (now redirecting) https://www.mongodb.org/display/DOCS to the pages they redirect to

One thing i was not sure on is where http://mongodb.github.io/node-mongodb-native/2.1/api/Cursor.html lead to, for now i have replace it to https://mongodb.github.io/node-mongodb-native/4.9/classes/FindCursor.html and for https://mongodb.github.io/node-mongodb-native/2.0/api/AggregationCursor.html to https://mongodb.github.io/node-mongodb-native/4.9/classes/AggregationCursor.html
