One of the i386 packages installed in the base Docker image depends on `python3-minimal` and APT tries to nuke the previously installed `python3` and all its friends, including `software-properties-common`, during the i386 package installation. Marking `python3` and `python3-apt` as held seems to make APT not want to do that, and keeps `python3` and its friends in place without any hacks. This should, hopefully, be the ultimate fix for all the i386 package dependency issues we have come across in the past. Signed-off-by: Stephanos Ioannidis <[email protected]>

We are no longer seeing the following error after this, so it seems to be working well for now ...
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
libglib2.0-dev:i386 : Depends: libglib2.0-dev-bin:i386 (= 2.80.0-6ubuntu3.4)
Depends: libglib2.0-dev-bin-linux:i386 (= 2.80.0-6ubuntu3.4)
python3 : PreDepends: python3-minimal (= 3.12.3-0ubuntu2) but it is not going to be installed
Depends: python3.12 (>= 3.12.3-0~) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
