fix(spec): the protocol-17 conversion summaries and three descriptions state their decisions in words

Stage 4 of the spec lane's runtime-string burn-down, class (b): the 56
toMajor-17 ADR-0087 conversion summaries (68 tracker ids) and three schema
and route descriptions (3 ids) now state what each cited decision was, or
drop a citation the sentence already explained. Text only: no conversion's
id, surface, step, transform or order changes.
