fix: remove duplicate translation keys in common.json (#27769)

Remove 4 duplicate keys that existed in the English translations file:
- routing_forms: identical duplicate removed
- submit_feedback: kept "Submit feedback" (consistent casing)
- skip_trial: kept "Skip trial" (used as button label)
- availability_schedule: kept "Availability schedule" (sentence case),
  removed duplicate with inconsistent capitalization

Fixes #23478
