Remove flaky Switch e2e test (#23410)

Summary:
'Switch that starts on should switch' appears to be flaky, as it has failed on seemingly unrelated commits, only to succeed on the next CI run. `Switch` is scheduled to be removed from the core repository anyway, so I'm removing this test to ensure we get a clear signal for the rest of the repository.

[GENERAL] [Changed] - Tests: Removed flaky Switch e2e test.
