docs: delete LABELS.md's scope table — the per-repo set lives in labels.conf and CONTRIBUTING

The mirror is byte-identical in every governed repo, so the four-row
enumeration was true at home and false in rig, box, cast and incubator —
14 of 16 vendored rows lied. The section keeps its doctrine and points at
the two places true wherever the reader stands; ceremony's own set is now
a pointer sentence in CONTRIBUTING, and a labels.test.sh row (red on main,
4 hits) keeps enumeration from returning.
