Updated Documentation for RequestLengthDiskThreshold (#12084)

- Fixes #12083

As noted in the issue, the value that is specified here is a value in KB, however, the documentation contained mixed references to both kilobytes and bytes.

I updated this to reflect properly kilobytes in all locations.

 ## Remarks
- The <xref:System.Web.Configuration.HttpRuntimeSection.RequestLengthDiskThreshold%2A> property specifies the input-stream buffering threshold limit in number of bytes. Its value should not exceed the <xref:System.Web.Configuration.HttpRuntimeSection.MaxRequestLength%2A> property value. After a request entity exceeds this threshold, it is buffered transparently onto disk.
