Do not exclude gz-common from focal ci_configs

[azeey]

ign-common4 (Fortress) is configured to run on focal, but we were excluding the abichecker from the focal ci_configs.

https://build.osrfoundation.org/job/gz_common-abichecker-any_to_any-ubuntu-jammy-amd64/ only triggers on gz-common5.

In fact, since we moved Citadel from Bionic to Focal we also need to remove the other exclusions:

        - gz-math
        - gz-plugin
        - gz-utils

This is going to have the side effect of making the branches shared by Garden (ci_config is focal) and Harmonic(ci_config is jammy) to duplicate the abichecker jobs. I'll open an issue and think the best way of dealing with this.

Thanks for the fix!

Can we merge this before we find a solution to #1095 to unblock https://github.com/gazebosim/gz-common/pull/559?
