Add docfx website for documentation

[banchan86]

This PR sets up the docfx infrastructure for documentation. Two points:

• I modified the GitHub actions recipe dotnet.yml, but not sure if its the right modification
• There is no GitHub Actions recipe added yet for online docs generation as it seems we are revamping the GitHub Actions workflow Use artifacts output layout and modern CI props zeromq#23 and I still need to learn how to do that.

Let's remove the TOC references to the non existing articles for a cleaner PR history.

Also, can we leave the packages at the top level without moving them to a src folder? This is the current standard that I am using and also what the bonsai core uses. Unless there has been a decision to use a different standard that I am not aware of.

I have removed the TOC references to the non-existing articles.

The Bonsai.Core probably isn't the best repo to emulate as it is structured quite differently from the other package repos (the docs is separated from the src), but the Bonsai.Core docs repo actually imports Bonsai.Core as a submodule under the src folder. The most recent Bonsai packages (Bonsai.Mixer, Bonsai.ML, Bonsai.PulsePal, etc) use this layout as well. But I have no strong feelings about it and the last commit moves the src back to the top level, @glopesdev can review and make the final decision.

Looks good, only very minor comments, and one thing I was starting to investigate is whether to add the favicon and logo directly to the template in docfx-tools or not.

It won't be used for all projects, but it could be set as the default in case no icon is specified, similar to how the DocFX logo itself is part of the default template and used if no other asset is defined.

@banchan86 looks good, maybe let's wait for the review and merge of bonsai-rx/zeromq#23 and we can review whether we want to bring over some of the patterns used there.
