sourceforge origins are scheduled specifically due to upstream's wishes at the time. Now
that the gist of the ingestion is done for those origins, we should get back to a
standard scheduling.

That means:

• reverting the commit that deactivates those origins in swh.lister
• stop the runners that specifically schedule those deactivated origins [1]
• sql: migrate back from enabled=false to enabled=true in the scheduler db (table listed_origins)
• let "standard" next-gen runner pick those up and schedule those origins
