Describe the bug
Currently section Development of documentation contains 3 items:

• getting-started,
• authentication, <<< this one is wrong
• external-url

But if we will click on authentication, we will be redirected to the overview/introduction.
It is because there is no such file exists in docs/development. It looks like authentication should be removed from the list (it is related to Deployment section and already present there).

Also probably 2 following items should be added to this section (at least such .mdx files are exists):

• installation
• overview

But before doing that, filenames and sidebarTitle/title should be aligned, because now:

• file installation.mdx has sidebarTitle: "Overview"
• file overview.mdx has title: "Quickstart"

It is little bit unclear which of thes files is really overview :)

*Please assign it to me if it will be confirmed that it should be fixed.

To Reproduce
Steps to reproduce the behavior:

1. Run documentation with mintlify dev
2. Find section Development on navigation side bar
3. Try to click authentication
4. You will be redireced to http://localhost:3000/overview/introduction

Expected behavior
Navigation should contain actual items only.
