Why Misnah Sanhedrin 4:5 and sura 5:32 is so similar

I somehow come across a Question in Quora that claim did Muhammad(sw)copied from Thalmud as Sura 5:32 and Misnah Sanhedrin 4:5 is too similar,I dont have much knowledge about it so after googling I told if Misnah is Oral torah than God just confirmed it in Quran but she show me this "English Explanation of Mishnah Sanhedrin 4:5:1" https://www.sefaria.org/English_Explanation_of_Mishnah_Sanhedrin.4.5.1?lang=bi , What does it mean?Was this jewish law created by jewish rabbi and not oral torah?She also mocked that Quran challenged no one would be able to produce a work like it but people already produced something like that way before Quran and Quran copied it. Actually what is this misnah sanhedrin and how to reconcile this with Quran?
