This task was created as part of this task: https://github.com/Yoast/non-dev-tasks/issues/39
See report in first comment to this task for context.

Blocked by https://github.com/Yoast/developer/issues/226 because links need to created to pages that are created in that task.

Supported Content types

In developer/docs/features/analysis create a folder called content-types.

overview.md

Within this folder we create one overview.md with some general information about supported content types and links to all specific docs in docusaurus.

The overview should have a docusaurus header like such:

---
id: contentTypeOverview
title: "Content Types: Overview"
sidebar_label: overview
description: This documentation provides an overview of the different content types we support.
---

List of content types:

• Post/Page/CPT
• taxonomy
• product/Shopify Product
• ...

content type specific pages.

---
id: postPageCPT
title: "Content Types: Post/Page/CPT"
sidebar_label: Post/Page/CPT
description: This documentation provides information on what assessments are available for Posts/Pages/CPTs and how they are available.
---

This could contain a table of all Assessments (with hyperlink to their docusaurus page that was created in https://github.com/Yoast/developer/issues/226) and some additional information

Think about whether other columns might be applicable to the table.

Review developer/docs/features/analysis and the documentation requirements in issue 226 first, since this task is blocked on links to those pages. Create the content-types folder with overview.md and content-type-specific pages using the shown Docusaurus front matter. Done means the overview links to each supported type and the pages document available assessments in clear tables.
