[Feature] Replace Swashbuckle.AspNetCore with NSwag

[sharky98]

Is your feature request related to a problem? Please describe.
Swashbuckle.AspNetCore has not been touched for over a year now and does not support .NET 8.0. Even the official docs were updated to flag this issue.

Describe the solution you'd like
There seems to be an alternative that is actively maintained, NSwag. The solution would be to update @nx-dotnet to use NSwag (or allow it under some configuration/flag) instead of Swashbuckle.AspNetCore

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Hi just came accross this. You should add it in https://github.com/dotnet/aspnetcore according to https://github.com/dotnet/templates?tab=readme-ov-file

I'd be open to a PR to handle this in our generators, but I don't have time to invest to do it myself right now.

@nithinbandaru1 I agree the template themselves should be managed by the dotnet templates directly. I was thinking more about the generators that uses the swagger command line. So I think this affect those: @nx-dotnet/core:swagger-typescript, @nx-dotnet/core:update-swagger, @nx-dotnet/core:add-swagger-target and @nx-dotnet/core:openapi-codegen
