jest example is missing explanation for `config` file

Discussed in #519

In this guide: https://github.com/nodkz/mongodb-memory-server/blob/master/docs/guides/integration-examples.md
there is no reference of config.ts file, it is used in both globalSetup and globalTeardown files.
why there is no description of this file in this guide? should I just remove its implementation from the setup?
