script/ptl-tool: add real QA-tag labels alongside nvme/orch/upgrades

'nvme', 'orch', and 'upgrades' never match a real GitHub label on
ceph/ceph -- verified via 'gh api repos/ceph/ceph/labels/<name>', all
three 404. Added the labels that actually exist -- 'nvmeof',
'orchestrator', and 'needs-upgrade-testing' -- alongside the originals
rather than replacing them, in case a future label reintroduces the
shorter/older name.

Cross-checked against .github/labeler.yml (commit a391fef144a7):
SUPPORTED_QA_TAGS still only covers 14 of labeler.yml's 27 categories.
13 more (mon, mgr, pybind, rook, bluestore, nfs, monitoring, telemetry,
documentation, api-change, CI, script, config-change) exist in the
auto-labeler but have no SUPPORTED_QA_TAGS entry. Left out of this
change deliberately -- several of those (documentation, CI, script,
config-change) aren't QA-testing-relevant categories, and expanding
the full list needs its own discussion.
