Check correctness of "Workflow for Verification Guidance" in verification concept

Within https://eclipse-score.github.io/process_description/main/process_areas/verification/verification_concept.html#workflow-for-verification-guidance there is a mentioning of hashes. It need to be cross checked, if this is implemented and that the respective requirements are created.

Text described is:

````
The :ref:`requirement_verification_workflow` above displays the whole workflow including the traceability concept for the
requirements where requirements shall be linked to test cases on the respective level. However also a statement
concerning the completeness of the test suite shall be generated. This means that also a linkage document shall be
generated including:

- the hash and UID of the requirement which was evaluated for test coverage
- the UIDs of the test cases which are required to fully cover the requirement.

So if the content of the requirement is altered also the hash will change making it necessary to
revisit the linkage of all test cases to the requirement again.

If the status of the linked test case and the linkage document is valid the attribute *testcovered* shall be set to *YES* during the SW Build.
Further information can also be depicted from the :ref:`requirements_engineering` process.
