Implement hands on hp-populate-remote

Exercise Discussion

This PR will close #56. Below is a more detailed description of the changes along with implementation notes:

1. Added an add_origin function in exercise_utils/git.py. This might be helpful in the future. I noticed that there is already a remove_remote implementation, and add_origin is intended to be used in a similar way.
2. To help ensure that the remote repository gitmastery-things is created successfully across multiple attempts, I added a check to delete any existing remote repository with the same name. Please note that this requires setting up delete access for the GitHub CLI via gh auth refresh -h github.com -s delete_repo. I also realised that the GitHub CLI needs to be configured beforehand for this part of the hands-on to work.

Note: The download script tested via test-download.sh works fine. Here is the remote repo I managed to create.

Checklist

• If you require a new remote repository on the Git-Mastery organization, have you created a request for it?
• Have you written unit tests using repo-smith to validate the exercise grading scheme?
• Have you tested the download script using test-download.sh?
• Have you verified that this exercise does not already exist or is not currently in review?
• Did you introduce a new grading mechanism that should belong to git-autograder?
• Did you introduce a new dependency that should belong to app?

This isn't an easy hands-on to implement because we have remote integration. Left a couple of comments on structuring the hands-on!

@damithc are we able to include this in our setup guide if it's not yet included?

This is already supported when you do __require_github__ = True: https://git-mastery.github.io/developers/docs/architecture/hands-on-structure/#file-structure

I think we can likely move this inline with this function. The function to get the full repo name is not used anywhere else

@woojiahao, it is actually used here as well. Is it okay to keep as is?

Thanks for the super-detailed comments! I’ll make the corresponding changes later today.

Sorry for the confusion, what I meant was that students need to have the GitHub CLI installed for the gh commands to work. I think it’s just an issue on my device since I haven’t used it before 😅.

Given having to delete a remote repo is rare, instead of deleting the repo automatically, a safer alternative is to abort with a message asking the student to delete the repo and run the download operation again after doing so.
WDYT?

I agree with this approach! If I understand correctly, this would mean the Python script in this repo should raise exceptions that the app’s download.py can then catch and print user-friendly messages, right?
