Summary:
Changelog: [Internal] - Port facebook/react-native/commit/cae063798652fcf394ccf3af4645fd971ed76c19 to main
This was something added to 0.65 branch when they were testing that release.
Comments from Lorenzo:
> When you do the local E2E test script a few times there are some files that get cached even if you try to be careful and wipe everything every time
but in particular during 0.64 when we were trying to investigate an iOS build problem we had inconsistency in repro because of caching because of the package name
so we introduced the extra "timestamp" in the name to avoid any "collisions" with existing caches
