From the article, it looks like the local police banned PUBG after locals complained about its addictive nature(in the exam season). Not saying that this is legit, but I don't think Modi would've called the local Police chief and said, "hey bro, please ban PUBG because kids won't do well in exams in my state".
As for the sites ban, I couldn't find any Government order banning these sites. For all we know, it might be the courts issuing these bans.
