Write Documentation on Inserting or Removing DOM Nodes

[stwrt]

Talk about how a node insertion or removal works.

@stwrt I've been working on the garbage collector docs, it will take some time, i think writing about node insertion and removal works will take only a day or two. I will update this doc in a time period of two to three days.

@stwrt should I create a seperate folder for this documentation or just add a single documentation file in the others section?

In the Deep Dive folder there should be a document called DOM.md.
https://github.com/WebKit/Documentation/blob/main/docs/Deep%20Dive/DOM.md

This would probably be the best place to put the notes for now.
