Replaced deprecated `node-sass` with `sass`

Since Bootstrap 5, recommended is to use [`sass`](https://www.npmjs.com/package/sass) library, as [`node-sass` is deprecated](https://sass-lang.com/blog/libsass-is-deprecated), even if we are still using Bootstrap 3 in the demo, this change should be considered.

`@javiereguiluz` (Sorry for the ping 🙏) Should I also resolve #1342 here?
