adding the Credentials file option back

[thedamian]

On friday we went through and talked about the remote url. and we used a credentials file instead of loading it from a .env

I'm suggesting adding back an example file and documentation in the mongoConnect.js file to show the students the different ways of getting the credentials and keeping it out of github

🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secret safely. Learn here the best practices.
3. Revoke and rotate this secret.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
