As others have said, she's not going to be brought back to life, because she never died in the first place. Her pendant was her life force, and sense it was not destroyed, Zelena didn't really die. Somehow she disguised herself as Marian or possessed Marian, and came back to the future with Emma and Hook. I'm almost 100% sure of this, just based on the BTS pictures we have seen.
