Changing to Core24 breaks docker setup

[osteenbergen]

Bug Description

Snapcraft 8 was based on core22 and now, without a mayor number change, it has switched to core24 breaking existing docker setups that use Ubuntu 22.04 as base.

We use Ubuntu 22.04/core22 as that uses Python 3.10 by default, matching our internal requirements for Python.

To Reproduce

See #5079 (comment) for example docker files

Environment

Docker image with Ubuntu 22.04 as base to build a Python 3.10 application

snapcraft.yaml

Not applicable as build environment is broken

Relevant log output

Additional context

Mostly this ticket is about why introduce a mayor change to snapcraft without upgrading the version to 9.x.

Fixing the docker file by adding core24 and probably fixing python related issues is likely doable.
