Update frappejs documentation about frappejs

[nickolay]

yarn add https://github.com/frappe/frappejs installs fine on node v12. Couldn't get through the rest of the docs though.

Looks like an interesting project
but documentation is very poor to get started

npm install frappejs
wont work if you are on current version of node (12+)
downgrade to node 10.15.1 and it installs fine.
this is due to frappejs being dependent on bcrypt 2.0.1

+1, I just wasted my day trying to installing Frappejs. This definitely should be added to the documentation.
