Broken link in articles docs

[tznind]

The link for 'TreeView Deep Dive' seems wrong (gives 404) in https://migueldeicaza.github.io/gui.cs/articles/index.html

It leads to:
https://migueldeicaza.github.io/gui.cs/articles/articles/treeview.md

but should be:
https://migueldeicaza.github.io/gui.cs/articles/treeview.html

It would be great if there was also a link to the table view article:
https://migueldeicaza.github.io/gui.cs/articles/tableview.html

Appologies if this is something I did wrong in my PRs

I applied the fix, but updating the docs now needs windows

I actually have PR almost ready.

I'm fixing some other things too...
