flightdeck → solid_queue-flightdeck

This gem has been renamed to solid_queue-flightdeck.

This final flightdeck version is an empty shell that depends on the new gem, so existing Gemfiles keep working. Update yours:

gem "solid_queue-flightdeck"

The mount point, configuration and Flightdeck module are unchanged.
