Update var.md (#4848)

In example 2 var is not required, its use makes the code more convenient. Without var a class could be created for the results. I will try to make a change to the comments in the example but I am not sure I can figure that out.

 ## Example  
- The following example shows two query expressions. In the first expression, the use of `var` is permitted but is not required, because the type of the query result can be stated explicitly as an `IEnumerable<string>`. However, in the second expression, `var` must be used because the result is a collection of anonymous types, and the name of that type is not accessible except to the compiler itself. Note that in Example #2, the `foreach` iteration variable `item` must also be implicitly typed.
