Inconsistent documentation for DbParameterCollection.CopyTo

I found an anomaly in the docs for DbParameterCollection ( [dotnet-api-docs/xml/System.Data.Common/DbParameterCollection.xml](https://github.com/dotnet/dotnet-api-docs/blob/master/xml/System.Data.Common/DbParameterCollection.xml) ). In the CopyTo method, the documentation claims that the values in the input array are copied to the collection. However, the documentation for the interface (IDataParameterCollection) and the documentation for SqlParameterCollection claim the values in the collection are copied into the input array.

I wasn't sure which way would be the expected behavior, and I didn't have time to read the .NET source code, so I wanted to document this. If nobody know off the top of their head, I'll try to loop back to research it out and fix it later :)

dotnet-api-docs/xml/System.Data.Common/DbParameterCollection.xml から始め、CopyTo の記述を IDataParameterCollection および SqlParameterCollection と比較します。.NET ソースを調査してコピーの実際の方向を判断し、その後、一貫していないドキュメントを更新して、影響を受ける API ページを確認します。
