The program fs-uae-arcade form the package of the same name requires
python3-requests, but does not list it as a dependency.

Installing fs-uae-arcade and running the program on a system without fs-uae-
arcade leads to the following Python stacktrace:
sys.path = ['/usr/share/fs-uae-arcade', '/usr/lib/python311.zip',
'/usr/lib/python3.11', '/usr/lib/python3.11/lib-dynload',
'/home/[...]/.local/lib/python3.11/site-packages', '/usr/local/lib/python3.11
/dist-packages', '/usr/lib/python3/dist-packages', '/usr/lib/python3.11/dist-
packages']

    import requests
ModuleNotFoundError: No module named 'requests'

Manually installing python3-requests fixed the problem, as expected.
