[Explore]: services/sitemaps: In sitemaps creation, added case for querying with subjects (instead of refine).

1. extractUrlsFromSearch.ts:
   a. Added input read for result type and for subject (can be given as empty).
   b. Added creation of sitemaps for results related to a specific subject (many methods are parametrized accordingly).
2. run.sh: Added a second parameter for subject.
3. .gitignore: Updated gitignore file to ignore sitemaps created locally in commit process.
