Fix: Invalid link on explanations documentation.

[jorgefilipecosta]

The section "What’s the difference between the different editor packages? What’s the purpose of each package?" does not exist anymore but the link to it was kept.
This PR removes the invalid link.

The section itself seems to exist.

https://developer.wordpress.org/block-editor/explanations/architecture/modularity/#whats-the-difference-between-the-different-editor-packages-whats-the-purpose-of-each-package

However, when I click on this link on the Explanations page, I go to the following URL and the page is not found.

https://developer.wordpress.org/block-editor/explanations/architecture/modularity.md/#whats-the-difference-between-the-different-editor-packages-whats-the-purpose-of-each-package

Perhaps if we remove the slash after the extension (.md), it will link correctly. All other links do not have a slash after the extension.

You are totally right @t-hamano, I noticed the modularity.md file had changed but I missed that the section was still there at the bottom. I fixed the link as suggested.
