Merge #13908: [Docs] upgrade rescan time warning from minutes to >1 hour

bb5b1c0b2d [Docs] upgrade rescan time warning from minutes to >1 hour (Mason Simon)

Pull request description:

  When I rescanned just now it took well over an hour. The time warning "may take minutes" didn't prepare me for that.
