Publish PDF version of RTD documentation

Made changes in the .readthedocs.yaml to enable format for downloading pdf and epub versions of the documentation and added latex_elements in the conf.py file which generates the pdf without blank pages. The minimum version requirement for sphinx was 6.2.1 which was causing build failure in read the docs, hence changing it 3.3.1 as written in setup.cfg of nexB/aboutcode
