Revert Ceph docs edit -- the problem was elsewhere

[jistr]

PR #363 made the Ceph docs slightly inconsistent and didn't seem to fix the docs issue we saw in #338 -- the problem is likely in that PR, here:

#338 (comment)

Let's revert #363 to make Ceph docs consistent again. I created a separate commit to fix the quoting issue in one of the snippets, i think we want to keep that.

@jistr Just so I understand the issue correctly, are you saying that we need the syntax to be "[source,bash]" or else the build breaks?

[jistr]

@klgill No, the issue was unrelated, it was missing end of the code block ---- in PR 338. Regarding [source,bash] i only put the state back into how it was before. I saw at least one other Ceph module has [source,bash], so it seemed random to remove it from that one doc, and i put it back to the original state before #363 was merged. #363 was merged only because we thought the CI was broken, otherwise we'd be looking at that patch more carefully i think.

So in conclusion, nothing of importance happened here i think 😁 . PR 363 landed and here we immediately reverted it after we discovered it wasn't the fix we were looking for.

We kept just this bit from PR 363 -- cbcf2db
