Fix test failure on differing precision of float in proto string

Problem: CI Pytest MacOS (3.10) fails because float value is output with a lower precision than in expected textproto. (https://github.com/quantumlib/Cirq/actions/runs/3192951160/jobs/5211002538) Solution: Update expected textproto to a lower precision and replace high-precision values in the tested string.
