t3olayout // node-sass@4.9.4 cannot be installed

Summary

When installing npm packages in t3olayout, sass is not being installed because the binary is not available.

user@ter-web:/var/www/html/private/typo3conf/ext/t3olayout/Build$ npm install

> node-sass@4.9.4 install /var/www/html/private/typo3conf/ext/t3olayout/Build/node_modules/node-sass
> node scripts/install.js

Downloading binary from https://github.com/sass/node-sass/releases/download/v4.9.4/linux-x64-72_binding.node
Cannot download "https://github.com/sass/node-sass/releases/download/v4.9.4/linux-x64-72_binding.node":

HTTP error 404 Not Found

Hint: If github.com is not accessible in your location
      try setting a proxy via HTTP_PROXY, e.g.

      export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

      npm config set proxy http://example.com:8080

Steps to reproduce

Setup project as described here, then, if you don't see the error upon ddev start already, navigate to /var/www/html/private/typo3conf/ext/t3olayout/Build and execute npm install.

What is the current bug behavior?

node-sass@4.9.4 is not available at GitHub anymore, which is: https://github.com/sass/node-sass/releases/download/v4.9.4/linux-x64-72_binding.node

What is the expected correct behavior?

Node-sass is installed properly. In addition I noticed gulp-sass installed either, so we probably have some duplicates here.

Acceptence Criterias

node-sass is installed accordingly. Not necessarily v4.9.4

Possible fixes

In the locked package file, node-sass v4.9.4 is locked. So, I assume it just needs to be updated.
