Favour Feliz in docs

[isaacabraham]

Docs like this one put Fable.React first. Yet we don't bundle Fable.React (as far as I know?) in SAFE 5 template and are using Feliz instead. Therefore we should flip them around.

1. Scan for all recipes for Feliz. Ensure Feliz is top over Fable.React.
2. Scan for all recipes using Fable.React. Replace with equivalent Feliz.
3. Instructions should be added on how to add Feliz (just the name of the Nuget package should be enough).

After mering #342, this issue can be closed

@Larocceau How did you address the last item (instructions)?

[Larocceau]

@mattgallagher92 there is a recipe for that: https://github.com/SAFE-Stack/docs/blob/master/docs/recipes/ui/add-feliz.md, but upon closer inspection that recipe is not great, because it references another recipe (add a NuGet package to the Client, that references another recipe (add a Nuget package to the Client), and does not explicitly state the name of the package. I'll create a PR for an update that is more to the point.

@Larocceau is there a PR that closes this issue or should I do that today?

[Larocceau]

@isaacabraham It was addressed in multiple PR's: #347 #346 #342, So it can be closed
