Increase iOS device test timeout on release branch (#19773)

Summary:\n- pass timeout: 120 to the iOS Device Farm test job in
apple.yml\n\nThis is needed because the v1.3.0-rc1 Apple run built and
uploaded the iOS artifacts, but the iOS device test was cancelled at the
default 60 minute mobile_job timeout.\n\nAuthored with Claude.
