Docs: document zone-based scanning; make version example non-drifting

The Scanning section only said 'per upstream OpenGD77', which left the
scan-list question unanswered. Explain that zones are the scan list, the
Zone Skip / All Skip flags, the start key and the Radio options settings.
Also replace the version example that goes stale every release.
