Member order in swagger.json

[maurei]

Member order in swagger.json should be: jsonapi, links, data, meta. However, having data in-between cannot be done using STJ on .NET 5. Solutions to consider: flattening the type hierarchy, using Newtonsoft instead of STJ or taking a dependency on .NET 6. Please create a tracking issue to address this.
