OpenAPI.NET 1.2.0 broke OpenApiString

[CumpsD]

microsoft/OpenAPI.NET#487

NuGet decided to install 1.2.0 in a project of mine which caused System.MissingMethodException: Method not found: 'Void Microsoft.OpenApi.Any.OpenApiString..ctor(System.String)'.

We need to upgrade to 1.2.0 to fix this, I'll make a PR later today
