Website feature: include sidebar, etc. from general TypeDoc theme

[JoshuaKGoldberg]

👋 I really like the idea of jsdocs-io - it'd be nice to switch ts-api-utils to not have to build its own docs (JoshuaKGoldberg/ts-api-utils#387). But, https://www.jsdocs.io/package/ts-api-utils doesn't have as rich of an output display as https://joshuakgoldberg.github.io/ts-api-utils or typedoc.org. I think that's a blocker for us to switch and a general usability issue for packages.

Specifically, the main navigation sidebars are missing:

• Left (site menu): the pages on the site
• Right (page menu): the headers on the page

Would it be possible to add these into the jsdocs.io package pages?

Hi @JoshuaKGoldberg, thanks for the issue!

On jsdocs.io all definitions for a package are on one page. Currently they are listed in the Index section at the top of a page, but I'm developing an updated experience for the site with a sidebar containing the exported types and quick search for fast navigation.

Right now, your package's page looks like this (WIP):

You can try it locally using the https://github.com/jsdocs-io/web/tree/with-astro branch, I welcome your feedback!

Oh hey, that's awesome! And it uses Astro - big fan. This is great. 😄

If that branch can hit feature parity with the tsdocs setup in ts-api-utils, I'd love to switch over.
