[landing] switch comparison order in CompetitorFeature

Summary:
Currently our comparison cards has an order where our competitor description is first then the Comm description comes afterwards. I felt that with this new differentiation section, and more generally too that it would make more sense to switch the comparison order to have the comm description go first then the competitor

Depends on D12629

Test Plan:
Confirmed that there were no regressions + please see the screenshots below
