_severely_ limit mechanism size to not crash github actions runners OOM

github actions runners have relatively limited memory

the mechanism size that would result from this would crash the runners with OOM errors when attempting to run cantera simulations

this fixes the issue by limiting the size of the mechanism. this does remove the scientific validity of the test, but at least covers some basic functionality and correctness checks
