Update Archive tests to be behind the USE_MATERIAL3 flag as well

These UI tests are currently only behind the `zip_ng_ro` flag, however,
the flag also gates on the `use_material3` flag. Unfortunately on some
devices without the `use_material3` flag check, the value is forced off
by the RRO. To ensure the tests run in their appropriate environment,
ensure the test is also gated behind the `use_material3` flag.
