Fix: add missing alt text to 6 images in DevOps mistakes post

[Anoopanil413]

What I found

6 of the 7 meme images in "The 10 Most Common DevOps Mistakes" had empty alt text (![](...)). Only the sloth GIF in section #7 had a description. Screen readers announce nothing for these images, and if an externally hosted GIF fails to load, nothing appears in its place.

What I fixed

Added descriptive alt text to the 6 images, written after viewing each one, to match the existing section #7 example:

Section	Alt text
4. No Rollback Plan	A man nervously pressing a big red button
5. Ignoring Observability	The confused math lady meme, surrounded by floating geometry formulas
6. Too Many Tools	Seth Meyers counting on his fingers and running out of fingers
8. No Documentation	Confused John Travolta looking around an empty room, captioned "Where is everyone"
9. Skipping Tests for Infra	A man cannonballs into a garden pond and lands flat on the frozen surface
10. Forgetting Security	Trojan horse meme: "Me" welcomes a "Random GitHub Action" into "My Pipeline" while soldiers labeled "Backdoor" hide inside
