Improve the docs based on the feedback

Documentation:

TODO

• [ ] Breadcrumbs: breadcrumb navigation at the top: so users can easily navigate to the previous page they were on
• [ ] Reorder it: It's well documented, but it would be better to have it ordered even in the sidebar. eg., frist "docs", followed by "Getting Started" or similar, and then others.
• [ ] Custom Domain: When I am adding a custom domain, it might be better to have some more info to explain how or some link to an external or an internal doc for explanation.
• [ ] Examples: More examples of charts and markdown templates for creating good documents
• [x] Markdown: Adding markdown instructions could be a cool thing. Added https://datahub.io/@olayway/docs/Markdown%20syntax%20support
• [x] Components: I was kinda lost to what exactly can be rendered or not, in regards to the markdown document and plots with plotly. Added https://datahub.io/@olayway/docs/Add%20visuals%20and%20data-rich%20components#what-features-are-supported

NICE-TO-HAVE

• Split the documentation: for regular users and developers and use a toggle like this one to switch between these 2 modes

• Next topic/previous topic: links at the bottom of each doc page: this will help the user maintain a sense of journeying through the docs, and they also know what comes next

• Relative path: add docs for multilevel structures and how to do relative path properly

• [ ] Notion: There is no info on how to publish a notion doc
