qa/suites/upgrade/reef-p2p/reef-p2p-parallel: increment upgrade to 18.2.2

Instead of installing 18.2.0, which still contains the osdmap crc bug tracked
in https://tracker.ceph.com/issues/63389, we should install v18.2.2 since this contains
the fix. Then, we upgrade to reef_latest. In this scenario, we do not expect to see the
crc bug. If we test any upgrade path before that, we will hit the warning and the test will fail.
