Increase execution_timeout for OpenAI tests that call the real API (#1466)

test_hello_world_agent[False] had a 5s execution timeout and
test_input_guardrail[False] had a 10s timeout, but both use a 30s
activity start_to_close_timeout. The workflow times out before the
OpenAI API call can complete on slower CI runners. Bump both to 60s.
