Documentation of FSimGate has incorrect phase convention

[kevinsung]

Description of the issue
https://quantumai.google/reference/python/cirq/FSimGate

The definition of c should have a negative sign in the exponent.

import cirq
import numpy as np

np.round(cirq.unitary(cirq.FSimGate(theta=0, phi=np.pi / 2)))

array([[1.+0.j, 0.+0.j, 0.+0.j, 0.+0.j],
       [0.+0.j, 1.+0.j, 0.-0.j, 0.+0.j],
       [0.+0.j, 0.-0.j, 1.+0.j, 0.+0.j],
       [0.+0.j, 0.+0.j, 0.+0.j, 0.-1.j]])
