There's something going on with the image cache on Cirrus where the images
are sometimes vanishing from the cache, thus causing builds to fail
because it can't load them. This forces a rebuild of all of the images,
thus refreshing the cached version of all of them.
The version of python included in the existing VM doesn't have the sqlite
module included for some reason. Forcing the VM to rebuild installs python311
which does include it, fixing a build failure.
