Docs: Move "An advanced example" from the HotColumn component page to another page

[warpech]

Description

At the bottom of the HotColumn component page (React docs), there is "An advanced example", which does not really fit this page well. It shows:

1. the use of HotColumn component (nothing unique compared to the examples above it)
2. a custom React component editor, which is also a custom React component renderer. This is unique, and not presented elsewhere in the docs. It better fits the "Cell editor" and "Cell renderer" pages
3. the editor and renderer mentioned above, uniquely use Redux, not the internal lifecycle of Handsontable, to manage the state. This is unique, and goes much deeper than the page "Integration with Redux". However, I am not even sure if we should present such usage. It goes against every other page in the docs.
