Blog - Relative links in blog truncated content (list view) are breaking #9731

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

Links such as [heading](#headingId) will work on the actual blog post page

But those links won't work on the list views where the blog is truncated with the {/* truncate */} marker.

This is because those relative links are resolved against the current page, and not the blog post permalink.

We should write a Remark plugin that will resolve the blog post links so that we have absolute links in list views, ensuring the links work in both list and detail views.

Example in production: https://docusaurus.io/blog/tags/search

This link doesn't work because the heading is not available on this page.

(I'm going to remove this example so it will not be browsable soon)
