Fix: rename sf36_root to sf36_root-san

[vjjda]

Filename at sc_bilara_data/root/san/sutta/sf/sf36_root.json should be sf36_root-san to be consistent

If I'm not mistaken, the source for this file is in the bilara-data repo, i.e. https://github.com/suttacentral/bilara-data/blob/cb390426c42504427e679271aa0dfb976c87894f/root/san/sutta/sf/sf36_root.json

Yes, but all bilara has the name format _root-{lang}. Another file at the same folder has the name follow the same format: https://github.com/suttacentral/bilara-data/tree/cb390426c42504427e679271aa0dfb976c87894f/root/san/sutta/sf

Because the of single odd case, I had to write some extra edge codes when parsing the data.
