Complement tech articles guidelines
What does this MR do?
Replaces https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/11220
-
Add publishing date to articles -
Link "article type" reference to its url -
Add exception for image filenames (as each article has its own /img/
folder) -
Add img guidelines: (a) compress all images, (b) only add img for illustration purposes only, not to replace its description.
The 2 first changes follow https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/10299/diffs?diff_id=4185967&start_sha=b69358d02e2c34625db797ec4d23f49dfa56164b, I made a separate MR for them.
The image ones come from https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/11149#note_29152846
