Switch back to python2 to fix issues (#67)

It seems as though this app isn't quite python3 compatible yet. This does the
following:

- Switch to using an AlmaLinux 8 so we can use python2
- Install git which is needed for the app to run
- Update requirements.txt to match current production

We need to eventually get this app and it's dependencies upgraded but this at
least allows us to migrate it.
