[FIX] actually build jammy, not bionic

Fixes: #121

Thanks, @StefanRijnhart! Very embarrassing copy-paste fail 🙈

Well, more embarrasment on my side, I'm now actually trying to build wkhtmltox for the first time myself, and it seems that Jammy needs to install python3 instead of python in its dockerfile. I can propose a fix (once I managed to run the build successfully myself), but what would be the best way to codify this? Would you like a new Dockerfile.debian.python3 with the packages swapped out?

Package python is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  python2-minimal python2 dh-python 2to3 python-is-python3

@StefanRijnhart I canceled the run to build the binaries. I think the cleanest way is to add an ARG python=python at the start of Dockerfile.debian and pass in python: python-is-python3 in build.yml which should hopefully pull in python3 as well.

Let me know if you figure it out, else I'll see if I can do it early tomorrow -- have a birthday in the family today 😄

[StefanRijnhart]

@ashkulz thank you for your guidance. Using an ARG for the python package seems to work. Will propose when the build has finished. Please prioritize family, it is important.
