Update gate jobs as per the 2025.1 cycle testing runtime

As per 2025.1 testing runtime[1], we need to test on Ubuntu
Noble (which will be taken care by depends-on tempest and devstack
patches to move base jobs to Noble) and at least single job to run on
Ubutnu Jammy (for smooth upgrade from previous releases).

This commit keep a scenario job to run on Jammy which can be removed
in the next cycle.
