Docs: give table pages a wider room and keep identifiers whole in cells

At the 52em measure a four-column parameter table is starved: the
browser squeezes the type column to 87px and breaks "string" as
stri/ng, relative_path as relative_p/ath — the wrap-anywhere rule
meant for prose overflow lets a table column shrink to almost
nothing — while a third of a 1280px window sits empty.

Two rules: a page that carries a table widens its article container
to 72em from 992px up (:has(), so prose-only pages keep their
measure; browsers without it keep today's rendering), and inside a
cell an identifier does not break mid-name, so columns are sized by
their longest name and the description column takes the surplus.
Measured at 1280px: the description column grows from 263px to
445px, and every identifier renders on one line.
