Running publisher with an API that has a VersionSet fails on an 'empty' APIM instance

### Release version

v6.0.1.1

### Describe the bug

When I run the publisher to upload all of my artifacts (one of the apis contains a versionSet into a 'clean' apim instance I get the following error stating that the ApiVersionSet not found.

```bash
System.Net.Http.HttpRequestException: HTTP request to URI failed with status code 404. Content is '{"error":{"code":"ResourceNotFound","message":"ApiVersionSet not found.","details":null}}'
```

### Expected behavior

Publisher would create the API with multiple versions correctly into APIM.

### Actual behavior

Error occurs trying to find the versionSet that is stored in the `apiinformation.json` file. Since it's an empty APIM instance it won't find the versionSet.

### Reproduction Steps

- Create an api that has multiple versions
- Extract that api into your git repo
- Run the publisher on a new APIM instance

Empieza reproduciendo la ejecución del publisher contra una instancia vacía de Azure API Management y, después, sigue la búsqueda de versionSet usando los datos de apiinformation.json. Comprueba dónde gestiona el publisher la ausencia de ApiVersionSet antes de crear APIs versionadas. La tarea estará terminada cuando la publicación de una API con varias versiones se complete correctamente sin el error 404.
