Adds one @course@ link to ten Docker roadmap topics, each pointing at a
tutorial that runs in a live Docker sandbox in the browser, and links the
full course from the DevOps roadmap Docker node.
Remove the 272 daily.dev "Explore top posts about ..." feed links
from 274 topic files across all roadmaps.
Three links were tagged @feed@ but are regular resources, so they
are retagged instead of removed:
- computer-science/sql-vs-nosql-databases: roadmap.sh guide -> @article@
- backend-beginner/git: YouTube crash course -> @video@
- game-developer/unreal-engine: Unreal Source Discord -> @article@
