Move reference_results.metadata into reference-results directory

fixes #537

Moved reference_results.metadata from tutorial root into the
reference-results/ directory to colocate it with the .tar.gz
files it describes.

Changes:
- moved metadata files into reference-results/ for all tutorials
- updated generate_reference_results.py to write to new location
- updated gitHub workflow git add pattern to match new location
