"Move Docker documentation under Developer Guide"

[man080107]

Description

This pull request reorganizes the Docker-related documentation by moving it from the "Topical Pages" section to the "Developer Guide" section of the book. The content itself is unchanged; only the structure and links have been updated to improve navigation and clarity.

Motivation and Context

Docker documentation is primarily developer- and deployment-focused, but it was previously listed under user-facing "Topical Pages," which caused confusion when browsing the documentation. This change places Docker documentation alongside other developer workflows, making the documentation structure more intuitive.

This PR addresses issue #3746.

Thanks @mdietze for pointing out the issue! I’ve fixed it and included the solution in PR #3748. Could you please take a look when you have time? Thanks!

I worked on the same issue but a beginner mistakenly opened a new PR #3749 instead of adding the fix here. Apologies for that
