Fix formatting of ArgumentOutOfRangeException

[rpetrusha]

The ArgumentOutofRangeException documentation displays causes of the exception by category, and then lists subcategories of that main category. The formatting of the page, however, doesn't reflect this. For example:

Here, "You are retrireving" should be indented one level, and "The collection has no members" should be indented two. This is a consistent problem in the topic which makes the exception troubleshooting advice extremely difficult to follow or understand.

Related to #2552, which includes some formatting fixes for this topic.
