Extend Test Setup

[wederbn]

Problem Statement:
Currently, only the workflow modeler itself, as well as the upload of workflow models to the Camunda engine are supported as test cases.
However, the integration tests with all other components (script splitter, hybrid program generator, Winery/OpenTOSCA, ...) are missing.

Expected Behavior:
The different components should be added as services within the GitHub workflows, and corresponding tests should validate the functionality of the integration.

Tasks:

• Add Winery to Testsetup #124
• Add Script Splitter test (check if workflow is generated correctly)
• Add Hybrid Runtime Handler (check if rewritten workflow has the expected structure)
• Add Pattern Atlas and QC Atlas (check if pattern-based generation and adaptation of workflows works as expected) #158
