docs: improve CodeSandbox integration

[layershifter]

Fixed bug 🐛

Fixes #3927. For some reason previously we got "https://react.semantic-ui.comhttps://react.semantic-ui.com" on CodeSandbox.

Update CodeSandbox icon

Previous icon was not correct which may confuse people.

👇

Integration improvements

• only required dependencies will added to package.json as not all examples use lodash for example
• range of dependencies will be now the same as in our package.json, semantic-ui-react's version will be the same as the current version of doc site
