Typo inside the jsdoc example

[maxime-bc]

Describe the bug

There is a typo inside the "Example JSDoc Config" section in the README.

The markdown object is a child of the opts object, but in the jsdoc-config.json the markdown object is a child of the root object.

As a result, when using the "Example JSDoc Config", links inside the "On this page" section referring to the README content don't work.

Steps to reproduce the behavior:

Use the "Example JSDoc Config".

Expected behavior

Links inside the "On this page" section referring to the README file should work.
