Minor grammar suggestions for installation of DragoNN AWS instance

[dylanmmarshall]

Hi there,

On this page (http://kundajelab.github.io/dragonn/cloud_resources.html), the step "Alternatively, you can run the Dragonn jupyter notebook by executing the following commands: sudo su passwd ubuntu enter your desired password when prompted." suggests that
sudo su passwd ubuntu is a one line command. For whatever reason, this step only worked when I separated sudo su and passwd ubuntu. Maybe it was just my system, but future users might run into this as well.

Additionally, in the README of the image, the outlined steps fail to mention that the notebook to be launched requires an account "ubuntu" with an associated "passwd".
