Bug Report

• Yes, I reviewed the contribution guidelines.
• Yes, more specifically, I reviewed the guidelines on how to write clear bug reports.

Describe the current, buggy behavior

In commands-manifest.json, few markdown_source URLs are not working. Eg:

• https:\/\/github.com\/wp-cli\/handbook\/blob\/main\/commands\/scaffold\/package-tests.md Ref
• https:\/\/github.com\/wp-cli\/handbook\/blob\/main\/commands\/scaffold\/package-readme.md Ref

Is this the reason pages like https://developer.wordpress.org/cli/commands/scaffold/package-tests/ not showing the docs properly?

Describe what you would expect as the correct outcome

Handbook pages should display correct and full command docs.
