Advanced Express Implementation of Social Authentication III - Deprecation for "findAndModify"

Describe your problem and how to reproduce it: I am using the latest boilerplate for the “Implementation of Social Authentication III” challenge on a server I control. When I copy and paste the code for the GitHub database record creation and run it, I get a deprecation warning:

(node:22140) DeprecationWarning: collection.findAndModify is deprecated. Use findOneAndUpdate, findOneAndReplace or findOneAndDelete instead.

According to the MongoDB manual page, the replacement function, findOneAndUpdate has been in place since Mongo 3.2. The boilerplate projects call out at least v3.6.

Deprecation notice: https://mongoosejs.com/docs/deprecations.html#findandmodify

The sample code in the challenge should be updated to use findOneAndUpdate. The signature appears to be identical and worked for my code.

Add a Link to the page with the problem: https://www.freecodecamp.org/learn/quality-assurance/advanced-node-and-express/implementation-of-social-authentication-iii

Haha, ok, I just figured that the signature was different, since my code failed, and I was coming here to update. Missed it by 4 minutes.
