Update the Server Rendering guide due to the changes in the Counter example

[forketyfork]

The Server Rendering guide refers to the Counter example to demonstrate adding SSR to a redux application. However, the Counter example was refactored since it was originally mentioned in the guide:

• It no longer includes the App container which is used in the guide,
• It was refactored to run with react-scripts without the server part. Adding a server side to this example now requires more work than is described in the guide.

While still providing the basic understanding of how to add SSR to a redux project, the guide now cannot be followed step-by-step, and probably needs to be rewritten using a different example.

Yeah, we've had a few people point out that there's some places where the tutorials in the docs don't match the example projects. I don't think any of us maintainers have time to make changes to those right now, but if you'd like to submit some PRs that fix things up, that would definitely be appreciated.

I’d like to update the Server Rendering recipe. Instead of using the Counter example, I thought of using the Todo List example as a base guide.

@markerikson Hi, what do you think about this idea?

[markerikson]

@ioboi : yeah, if you're interested, we'd definitely work with you to get updates into the docs.

So rewrite a counter App that is SSR? is that what needs to be done along with explaining SSR

I don't have the time anymore, sombody else can take the issue.
