Continue creating Debian i386 images

[cquike]

We have been using LXD Debian i386 images for testing our software in that platform. However it looks like now the LXD images are not available anymore. Would it be possible to get those images again? At least for the supported Debian versions bullseye and bookworm. I understand that in the future Debian itself might drop support for i386, but until then this is useful, it has allowed us to catch errors from time to time due to numerical differences between platforms in our tests.

As it stands, we're not very likely to reintroduce them as they were literally doubling our storage and distribution (to mirrors) cost, requiring a bunch of workarounds to build them (as Ubuntu which is our CI platform no longer supports i386) and were use by so few users that it wouldn't even register in usage statistics (total daily image downloads in the 500k range, 32bit image downloads in the 50-100 range).

We haven't modified our YAML files yet though, so producing those images for yourself locally should be pretty straightforward.
