Reddit feedback on Blazor docs

[guardrex]

From @IEvangelist via offline thread ...

I saw a reddit thread about Blazor today, and some of the comments have some feedback about the docs and suggest making some changes to make it easier to figure out how to do different things based on the render mode.

A significant portion of the feedback pertains to framework design issues, which would need to be opened for the Blazor engineers on the dotnet/aspnetcore repo. I'll analyze our coverage for the subjects discussed and see if improvements can be made in the documentation.

There's been work in some of the areas covered by the post with on-going work to address a few items via existing issues. For example, prerendering coverage had one round of updates and is being addressed in a second round of updates right now. Some of the areas aren't actionable here because they have to do with framework design and should go to the PU in one or more PU issues. Some of the mentions are already covered well (IMO). I'll close this, and the Reddit discussion participants are welcome to open new issues on this repo as needed.
