Tutorials need to specify `rimraf` dependance?

[nuke-web3]

Describe the Bug

On using the tutorial #57 as a start, using npm run build yields an error. Just need to add a note to run npm install in the docs first

> rust-webpack-template@0.1.0 build ........
> rimraf dist pkg && webpack

sh: 1: rimraf: not found

Expected Behavior

Default templates should compile 🙏
