Debian stable is more or less an alias #237
Description
Comparing the InRelease files for :stable and :bookworm its pretty clear that they are the same file (at the moment). It would probably be a good idea to treat stable as a alias for bookworm, because:
a) one image less to build
b) less confusion why @sha256 of bookwork and stable is different
c) no problem with people comparing timestamps and wondering which is more recent
d) its obvious from the tag list where stable points to
Instead of treating it hardcoded, its probably best to just resolve the alias url and check the codename in the InRelease file.
