Setting all H2's in carnation based on 'node--view-mode-full' makes it hard to override H2's

Instead of removing the h2 I just scoped it better to what I thought it was meant to style.

See https://sandbox-carnation-cus-d9.y.org/locations/downtown-ymca under Schedules > "Classes and Activities for the branch:" is now the only h2 that this style applies to.
