Full And Sanitized Node Documentation

Is this a question?
No

Can this functionality be implemented utilizing API?
Not a functionality per say.

Is your feature request related to a problem? Please describe.
Many functions of the API retrieves nodes such as get_node_under_cursor().
There doesn't seem to be any documentation about the structure of a node except in the sort API section. But there are some missing fields in the doc.

Describe the solution you'd like
It would be nice to have a small section of the documentation dedicated to the content of a node. This would make it officially part of the API.

Describe alternatives you've considered
Check the node builder source code but that does not prevent invisible breaking changes to the node API.

Additional context
This issue is raised after a short post on reddit.

I don't know if this qualifies as a feature request, feel free to move it around.

nvim-tree is an awesome plugin and you did a really good job.

Start with the node structure shown in the sort API section of doc/nvim-tree-lua.txt and compare it with lua/nvim-tree/explorer/node-builders.lua. Document the full and sanitized node contents as part of the API, including the fields found during that comparison; done means the documentation clearly describes both node forms and their supported fields.
