gtk3.22: Small Font changes not taking effect
Fix to all branches, including S2_6, attached.
Later branches have minor translatable string change that's left out from S2_6 (in permanent string freeze) and S3_0 (not in freeze, but regardless the change is not important enough to break the translations)
While looking around for #48185, I noticed that at least the building list in city dialog does not react to the changes of the Small Font setting. Seen on main branch.
