Add patch script to enable E2E tests in CI (#46546)

Summary:
This chang introduces a patch file that can be applied to run the E2E tests in CI.

From the root folder `react-native`, a user can just run:

```sh
git apply packages/rn-tester/scripts/enable-e2e-tests.patch
```

And then add a commit to their PR to see whether the newly added E2E tests are actually running

## Changelog:
[Internal] - add patch to simplify running E2E tests in CI
