I just take it as the SNW version of the Gorn are a different species of Gorn. Same with the ENT version.
The Kelvinverse Gorn were featured antagonists in the licensed computer game and they had tails similar to the SNW Gorn. They were said to have stepped through a gateways from a parallel universe.
There was even a Lego-like figurine (Kre-on figures) released of the Kelvinverse Gorn.

Mego’s brown Gorn (8” action figures in Klingon uniforms) from the 70s have even been seen in a fairly recent comic mini-series by the Tiptons (for IDW), set in the Mirror Universe.

Plenty of possibilities, especially considering all the canonical clines of Klingons, Romulans, Andorians, Tellarites, Betelgeusians and Trills we have seen.
