Revert "[v9.5.x] [feat] docs; update admonition syntax (#68856)"

This reverts commit 08ea5c94c6.

I believe that because of automatic conflict resolution, this backport PR contained a number of extra changes that were not part of the update to use admonition syntax.

I'm first going to revert this PR to prevent the confusing behavior in PRs like #68832.

If we still want admonition changes backported, we can open a new PR which I would like to be a reviewer on to double check.
