Optimum neuron 0.2.2 (#3281)

* chore(neuron): use optimum-neuron 0.2.1

* test(neuron): adjust expectations

Since the latest optimum-neuron uses a new modeling for granite and
qwen, the greedy outputs are slighly different.

* test(neuron): add phi3 and qwen3 tests

* chore(neuron): use optimum-neuron 0.2.2
