fireEvent(element, 'press') is a no-op on a relation-free Pressable since 3.2.0 #4417

Description

Since 3.2.0, fireEvent(element, 'press') from React Native Testing Library silently does
nothing on a plain <Pressable onPress={...}>. No error is thrown — the handler is simply never
called, so assertions report 0 calls and any waitFor around the press runs until it times out.

This is a test-environment-only bug; runtime behaviour on device is unaffected.

Cause

3.2.0 split Pressable into two engines
(v3/components/Pressable.tsx):

• StatefulPressable when one of simultaneousWith / requireToFail / block is passed
• PressableWithTouchable otherwise — the common case

StatefulPressable sets testOnly_onPress / testOnly_onPressIn / testOnly_onPressOut /
testOnly_onLongPress on the button
(StatefulPressable.tsx#L463-L466).
PressableWithTouchable does not. Since the press state machine runs natively, those props are
the only way a test environment can reach the handlers — RNTL looks them up in
event-handler.ts.

In 3.1.0 the single v3 Pressable always forwarded them, so this is a 3.1.0 → 3.2.0 regression
for any app whose Jest suite drives a Pressable.

This is unrelated to #4414, which fixed the testOnly_pressed display state.

Expected

fireEvent(element, 'press') calls onPress, as it did on 3.1.0 and as it still does when a
relation prop is present.

Fix

PR #4416 forwards the four handlers from PressableWithTouchable too, guarded by isTestEnv(),
exactly as StatefulPressable does, and adds a regression test that fails on main.

Steps to reproduce

1. In an RN project on react-native-gesture-handler@3.2.0 and
   @testing-library/react-native@>=13, make sure jest.config.js has
   setupFiles: ['react-native-gesture-handler/jestSetup.js'].
2. Add the test file from the repro link below.
3. Run it.
4. The first test fails with Expected number of calls: >= 1 / Received number of calls: 0; the
   second one — identical apart from a simultaneousWith prop — passes.
5. Downgrade to react-native-gesture-handler@3.1.0 and re-run: both pass.

The bug only exists under Jest, so a device reproducer would show nothing — the failing test is
the reproduction. PR #4416 also carries a regression test that fails on main.
