www: Create script migration example (#21437)

moving away from calling people "leads", it's weird

this continues the effort of making it so that leads are more like a:
"dear fleeties, you have to do something"

Now, lead sources are effectively GA conversions, and will eventually
change to just be auto-created stage0 opportunities, and even then only
for booked meetings where there's work that a fleetie needs to do to
make sure and prepare a useful demo for the folks on the other end, so
they can present Fleet internally while spending as little time talking
to us as possible.

So that's the end of lead sources.

Whereas compare w/ user actions, which are now captured as either
contact creation (contact source), contact psychological progress (most
recent psystage change reason), or opportunity creation (opportunity
source).
