Revert "ci: use newer docker image based on noble"

This reverts commit e63d92f0fdec6e825826ef74454cd2d9b0641d1d.

Reason for revert: The CI jobs was suspended waiting for the
the nodes to be created.
This couldn't be understood from the infrastructure, so reverting
until we can further investigate.
