chore(nginx): do not force trailing slash
This prevents nginx from automatically redirecting to the slash-terminated URLs for pages.
Steps to reproduce
- Visit https://design.gitlab.com/layout/grid
- Observe redirect to
/layout/grid/(trailing slash added) - Visit https://4456656-review-do-not-for-pzqdfc.design-staging.gitlab.com/layout/grid
- Observe no redirect
🎉
Closes #620 (closed).
