go.mod: bump osbuild/images to c2aa82cc9a86

images 0.1.0 and 0.2.0 were already released, but they are incompatible with
osbuild-composer's test suite. However, we need to support F40 as soon as
possible. This commit as a workaround: it bumps the dependency to a new enough
version that has Fedora 40, but it's old enough that it doesn't have
the breaking changes.
