bug: entity resolver argument parser fails to unwrap list values

[dariuszkuc]

Reference resolver currently fails to map @keys that specify list fields. ArgumentParser is currently missing case for SyntaxKind.ListValue so whenever we have to process representation with list values it is unable to locate the target resolver.

[Key("ids")]
public class Foo
{

    public Foo(List<string> ids, string? name)
    {
        Ids = ids;
        Name = name;   
    }

    public List<string> Ids { get; }
    public string? Name { get; }

    [ReferenceResolver]
    public static Foo? GetFooByIds(
        List<string> ids,
        Data repository)
    {
        // TODO implement logic
       return null;
    }
}

Workaround is available, instead of doing the auto mapping of arguments we process representation manually

    [ReferenceResolver]
    public static Foo? GetFooByIds(
        [LocalState] ObjectValueNode data,
        Data repository)
    {
        // TODO implement logic by manually reading representation from data
       return null;
    }
