Update C++ TOC and update settings links

[AlexandraKemperMS]

Removed references to the settings page (which has changed names at this point) and updated the TOC since now an additional level of nesting is supported. The debugging docs have been put under one header - this will be updated more as these docs are changed. I will double check with the CMake team about the CMake docs

Good work

@AlexandraKemperMS When you create subnodes in the ToC, make sure to:

• Update the area for the subnode
• Create a corresponding folder in the repo and move the articles in there
• Update the link to the articles to include that subfolder

The process is still a bit different from that on MS Learn...

I took another stab at it - let me know if this is what you meant or I need to make more edits!

@AlexandraKemperMS Thanks for the updates. The only change needed is to rename the folders to match the values of the area field.

I'll update the contributor guidance to make it clearer.

@AlexandraKemperMS I didn't make myself clear enough. The actual folders within the docset need to match the area value, so they need to be renamed as well. For example, "Getting Started" -> "gettingstarted"
