I am suggesting we upgrade to the latest version of Mongoose, which is now version 7 https://github.com/Automattic/mongoose/releases

We wish to upgrade so that we have make use the latest features, bug-fixes, and security patches in the mongoose package.

Currently, as per my understanding, @nestjs/mongoose has dev dependency on mongoose version 6.10 with a peer dependency on version 6.0.2

Describe the solution you'd like

I would like @nestjs/mongoose to depend on the latest version of mongoose version 7

Teachability, documentation, adoption, migration strategy
