Doc: "Get Started" guide on using custom themes is outdated and misleading

[zmwangx]

On https://react.semantic-ui.com/usage, under the "Custom Theme" tab of the "Theme" section, the recommendation is

The Semantic UI package installs a Gulp build tool that will walk you through creating a custom theme within your project. Install this as a dev dependency:

$ yarn add semantic-ui --dev



After building a theme with Gulp, include the minified CSS file in your index.js file:

import '../semantic/dist/semantic.min.css

Detailed documentation on Semantic UI theming is provided here and in our Theming guide.

Unfortunately, semantic-ui is stuck on Gulp 3 and incompatible with Node 12 (Semantic-Org/Semantic-UI#6818). This sent me on a wild goose chase that ended nowhere; then I checked the Theming guide which is based on semantic-ui-less and works without a problem.

So, the semantic-ui mention is misleading and kinda does this project a disservice. Would you please update that section? Thanks.
