AspNetCore.OpenApi support

[CheloXL]

Describe the feature

Now that .net 9 is out and Swashbuckle was removed, it would be nice to have support for the new AspNetCore.OpenApi.

Hi @CheloXL - this should already be supported https://stevedunn.github.io/Vogen/use-in-swagger.html

Please let me know if there's anything missing

[CheloXL]

Yes, but no, but yes, but no. SwaggerOptions is swagger specific. In .net 9, swagger doesn't exist anymore (of course you can still use it, but I would prefer to migrate to the native support). So, this feature request is to use .net 9 specific open api support.

I see, good point! Thanks for the feedback.
