Merge master into doc-refactoring: resolve conflicts and fix build paths

- Resolve .gitignore conflict (keep both sides' additions)
- Update vfbterms.py datasets path from '../datasets/' to 'datasets/'
  to match new ontologies location at blog/ontologies/
- Add datasets/_index.md under blog/ontologies/ for term page generation
- Remove accidentally staged __pycache__ file
