Recap - Merge Master

The folder contains menu.txt and about.txt, both with one line each.

Walk through this scenario:

1. Initialize the repo, configure user, and create the first commit with both files.
2. On a branch menu-update, append burgers to menu.txt and commit with message Add burgers.
3. Back on main, append contact info to about.txt and commit with message Add contact info.
4. Merge menu-update into main with the merge message Merge menu update.
5. Print the contents of both files (menu first, then about), concatenated by cat menu.txt about.txt.
