venture: start a new venture whenever you like

The schedule starts one venture card a day, and Run workflow only
advanced the cards already open. Run workflow now has a "Start a new
venture now" checkbox (gh workflow run venture.yml -f start=true) that
opens a fresh card even when today's has run; a second card on the same
day is titled "Venture <day> (2)". The schedule is unchanged.
