[backport core/1.34] style-fix: Don't add body padding with no body. (#7523)

## Summary

Backport of #7424 to core/1.34.

Small fix for collapsed nodes - don't add body padding when node is
collapsed.

### Changes
- Removed unconditional `pb-1` from node base classes
- Added conditional `!isCollapsed && ' pb-1'` to only apply padding when
node is expanded
