README.md needs updating to show full range of supported OSes

[alansill]

Initially I was discouraged abut installing this as I don't use Debian or Ubuntu on most of the SBC systems in our student lab, so instead set about installing each of the components separately. After each of these installed fine on their own, I got inspired to go back and try to install the full project. It worked fine for me out of the box with Rocky Linux 9.4 and ran just fine to completion on the Apple Mac Intel i7 mini that I was using for the test.

I'd be happy to put in a pull request to update the README.md but don't know the full range of operating systems this tool will support. At minimum, the documentation should be updated to show more OS options if a full range is known.
