Reduce Image size in Content area

[Pokrel]

Problem:
If you go to the page DevOps -> DevOps Intro, and you will see that the ci-cd image is over lapping the content area.

Solution idea:
After forking and cloning the repo. Go to main/docs/pages/devops_intro.html. Line 14 is the actual code for the image. Probably this' where you should add some code for the image size. Feel free to implement any alternative idea you have and test it before the commit request.
