fix: keep the date and Next steps out of search

A query word matches the start of a longer word. Since the index grew,
the "2" of "playstation 2 bios" matched the 2026 of every page's date
line and the "u" of "wii u bios" the "use" of Next steps, so the
PlayStation and Nintendo pages held every query word and ranked above
the PlayStation 2 and Wii U pages. Both blocks carry
data-pagefind-ignore now: search_gate answers 58 of 58 queries, the
four console pairs by 9 to 14 percent. Batocera's pages weigh 882
bytes more for it.
