DOC: update make.py script
@TomAugspurger I updated the docs yesterday with this.

Not sure if it is needed to keep the possibility to pass a user (if you specify this in `.ssh/config` you don't need this, but the current code allows you to not have the user specified there) 
But I could also simplify and just remove the whole user thing.

(depending on that will also update the other one, upload_stable_pdf)
Thanks.

I should probably just make a `pandas` user on the server that we all have the ability to ssh into. > I should probably just make a pandas user on the server that we all have the ability to ssh into.

Not sure if it is that useful? Because you would still need to add a key for everybody wanting to access it no? (and I suppose adding a new user is also not that much of work?)
