JsonParseNode.GetCollectionOf* methods now return null when called on non array types

[Irame]

The Methods GetCollectionOfPrimitiveValues, GetCollectionOfEnumValues and GetCollectionOfObjectValues in JsonParseNode now return null when called on a non array type.

For this to work the changes from microsoft/kiota-abstractions-dotnet#174 are neccessary.

This change is part of the solution for the problem discussed here microsoft/kiota#3976.
