Fix 'CHT API' & 'Partials' about cht-docs HOT 2 OPEN

Local docker setup too!

For future reference, the Docsy theme that we use makes it possible to omit pages from the lefthand table of contents and the index page summaries with instructions in the front matter:

To hide a page or section from the left navigation menu, set toc_hide: true in the front matter.

To hide a page from the section summary on a docs section landing page, set hide_summary: true in the front matter. If you want to hide a page from both the TOC menu and the section summary list, you need to set both toc_hide and hide_summary to true in the front matter.

I've also noticed experimentally that ommiting front matter altogether makes the page not show up in TOC and Index, but it is not clear if that will always be the case, so better to use the specified instructions.
