fix(docs): keep the base path on internal links

{% link %} returns a path without the project base, so the header API
link and every in-page link went to feildmaster.github.io/api/... instead
of /UnderScript/api/.... Prefix them with site.baseurl like the API
layout already does, and do the same for the index screenshot.

 ## Editor support
 Starting with 0.65.0, every release has a file called `underscript.d.ts`. It is optional, and plugins work the same without it, but editors like VS Code use it to suggest and check your code. Download it from the [latest release](https://github.com/UCProjects/UnderScript/releases/latest) and put it next to your plugin's script.
