[DOCS] Improve official documentation structure

[Marcel-TO]

Documentation Issue Type

• Typo or grammatical error
• Incorrect or outdated information
• Unclear explanation or confusing content
• Missing documentation for a topic
• Broken links or images
• Code example not working
• Other (please describe)

The current NPC documentation contains everything inside 1 page that is multiple thousand lines long with hundreds of sub headers. It would be a good idea to maybe structure the multiple headers into separate npc documentation pages

Location

Page/File: content/docs/official-documentation/npc-doc.mdx

Current Content

As mentioned above, this documentation is quite long and causes to loose train of thought.
