README is missing info about webpack / npm / node

[TimidRobot]

Describe the bug

There is no information on webpack's dependencies in the README.

(Webpack is invoked via lektor/lektor-webpack-support)

Expected behavior

At a minimum, there should be information about what is required on macOS using Homebrew.

Information for GNU/Linux would be nice to have.

Webpack dependencies are tracked via package.json: https://github.com/creativecommons/creativecommons.github.io-source/blob/master/webpack/package.json

@TimidRobot Do you mean the dependencies required to install webpack (namely node and npm) are missing in the README?

If yes, then I will like to work on this issue and add them up
