Verify that NSwag would support .NET's new Description property on [ProducesResponseType], [Produces], and [ProducesDefaultResponseType] Attributes

[sander1095]

I'm currently working on dotnet/aspnetcore#55656, which adds a Description property to the attributes mentioned in the title.

I had a quick look through NSwag's codebase to see if it would need any updates to get Description support. However, I believe this is not the case as NSwag grabs all the attributes and looks for Description properties on them. Currently, this would not match with ProducesResponseType, but when the mentioned issue's PR gets merged and released (probably in .NET 10), it will automagically work.

NSwag/src/NSwag.Generation/Processors/OperationResponseProcessorBase.cs

Line 152 in 7d6df3a

if (attributeType.GetRuntimeProperty("Description") != null)

The goal of this issue is to verify that this is the case.
