Added e2e test case for 3.5 for #14571

@ahrtr LGTM, thanks a lot for creating the e2e test case! I tested that not refreshing range perm cache can result in failure of the test on my env. I think it's also valuable to add the test case to the main branch?

@veshij already added e2e test on main branch in #14574. release-3.5 has huge difference from main branch, and there is no easy way to backport the e2e test to release-3.5. So I have to add a new e2e test for 3.5.

Sorry I compared the e2e tests and checked that they are essentially testing the exact same scenario, I misunderstood about how to trigger the condition of the issue.
