page.json: fold the "Tab" entry into pin 2. On SOT-223-3_TabPin2 the tab is not a separate pad - it is that lead - so nothing was ever unconnected, but the page listed it as its own pin and pads.json reported pin-not-in-symbol for a pin that cannot exist. Target chosen because net OUT matches pin 2; the tab's description is merged into that pin rather than dropped.
