docs-gates: widen smoke retry envelope for worker-version propagation (5 rounds x 30s)

The merge-triggered smoke run for the round-based retry work failed on a
worker-version propagation race that outlasted the 3-round x 20s envelope: all
probes were served the previous SHA through rounds 1-2 and one path (cli.html)
was still stale at round 3 (2 sleeps x 20s = 40s insufficient).

Widen to MAX_ROUNDS=5 / RETRY_SLEEP_SECONDS=30 -> 4 inter-round sleeps x 30s =
2 min, covering the observed 1-2+ min propagation waves. The green path is
unaffected (no retries -> zero added time); DEADLINE_SECONDS=480 still bounds the
worst case. Tests read the constants dynamically (monkeypatch), so none pin the
old literals.
