[Bug] GitHub Foundations - 'Exercise - Add a .gitignore file' is unrelated to this repository and its purposes

[rjceledon]

Summary

In the module Maintain a secure repository by using GitHub best practices from the GitHub Foundations training guide, it specifies that this exercise including some training for Exercise - Add a .gitignore file. However after forking the repository and checking the READMEs, this exercise does not include any training about .gitignore files, but rather is training regarding code vulnerability and other stuff. This seems to be unrelated with the previously mentioned module, therefore the training module should be updated and include a valid exercise, or this exercise should include something related to .gitignore files.

How to reproduce

1. Go to https://learn.microsoft.com/en-us/collections/o1njfe825p602p
2. Click on https://learn.microsoft.com/en-us/training/modules/maintain-secure-repository-github/?ns-enrollment-type=Collection&ns-enrollment-id=o1njfe825p602p
3. Go to Unit 3 https://learn.microsoft.com/en-us/training/modules/maintain-secure-repository-github/3-security-strategy-essentials/
4. Follow the steps

Additional context

This is not specifically a bug, rather a mismatch between the module and the exercise.
