Sidebar dropdown icon, and DocCardList, still recognise "unlisted" child documents

Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Prerequisites

• I'm using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io.
• I have read the console error message carefully (if applicable).

Description

Given I have a document structure like this:

my-folder/
  index.md
  some-unlisted-doc.md
  another-unlisted-doc.md
  third-unlisted-doc.md

and all child documents except index.md have "unlisted" annotations:

---
unlisted: true
---

The sidebar dropdown caret and the DocCardList components still behave as if there are listed child pages.

The dropdown caret does nothing as child pages are unlisted.

Expected behaviour: those pages are unlisted so there should not be any recognised child pages.

Reproducible demo

No response

Steps to reproduce

1. Add unlisted child pages to a folder with an index.md page
2. Open the docs page

Expected behavior

Dropdown caret should not show, DocCardList should render index.md contents

Actual behavior

It behaves like it should with listed child pages

Your environment

• Docusaurus version used: 3.7.0

Self-service

• I'd be willing to fix this bug myself.

While attempting to reproduce, I found that the unlisted pages are showing in the sidebar also: https://codesandbox.io/p/devbox/crimson-bash-2mprf8. I don't experience this locally.
