[BUG] Error when Set Variable from Json data

## Description

Set Variable it is not working when you try to set a value from a HttpRequest response

## Steps to Reproduce


- Create an workflow definition
- Add a http request and save the parsedcontent in a variable of type Json(dynamic)


Following json returned from the http request

`{"results":[{"id":1,"name":"Item A"},{"id":2,"name":"Item B"},{"id":3,"name":"Item C"}]}`

- Add a set varaible after the http request, using a c# expression to get the property of the json
`dynamic responseFromHttp = Variables.JsonData;

return responseFromHttp.results;`


when execute give the following erro: (3,8): error CS0656: Member “Microsoft.CSharp.RuntimeBinder.CSharpArgumentInfo.Create” required by missing compiler

3. **Attachments**:
Included the workflow definition
[request.json](https://github.com/user-attachments/files/16626239/request.json)

Start by reproducing the workflow from the attached request.json: an HttpRequest stores parsed JSON, then Set Variable evaluates the C# expression using Variables.JsonData. Trace the reported Elsa.CSharp.Services.CSharpEvaluator and Elsa.CSharp.Expressions.CSharpExpressionHandler entry points to identify why dynamic access lacks the runtime binder; done means responseFromHttp.results evaluates successfully without CS0656.
