fix(web): regenerate facts.generated.ts for the two v0.9.8 providers

53af08c registered Google Gemini and 531b64e registered Google
Antigravity, but web/lib/facts.generated.ts was never regenerated, so
check:facts has been failing on main since the release. That gate is part
of Lint & Type Check, which makes it a required check every web pull
request inherits regardless of what it changes.

Output of `cd web && npm run prebuild`, which is what the checker itself
suggests. derive-facts.mjs reads the Rust sources directly and needs no
build. The diff is the two provider rows plus generatedAt; the script
preserves that stamp unless a checked fact moves, so it moving here is the
signal that one did.

Same family as #5383 (assertion counts) and the docs/PROVIDERS.md row in
#5394 -- this is the remaining artifact those two commits left stale.

Verified by hand: check:facts, check:locales, check:docs and lint all exit
0, run twice. vitest is unchanged at 10 failed / 250 passed, byte-identical
to the same suite on an unmodified ad102ec -- seven Cloudflare
deploy-preflight tests that need credentials, and three changelog and
release-facts parity tests that this regeneration does not address.

Analysis drafted with local tooling; every change and test verified by hand.

No-Issue: unbreaks the check:facts gate on main; the drift itself is
already covered by the v0.9.8 follow-ups.
