### What happened?

I have quite a number of endpoints, which makes the documentation's index.html file quite large and causes it to hang in the browser. Is there an option to split the documentation into multiple pages rather than have one big index.html?

### Docs

- [x] I've checked [the docs](https://scribe.knuckles.wtf/laravel), the [troubleshooting guide](https://scribe.knuckles.wtf/laravel/troubleshooting), and [existing issues](https://github.com/knuckleswtf/scribe/issues?q=is%3Aissue+), but I didn't find a solution

Start by examining the static documentation output, especially the generated index.html, and trace how its endpoint content is assembled. Determine whether multiple pages can be generated without breaking navigation, then verify that large API documentation loads without the browser hanging.
