Description of the problem:

Second or later workflow execution contains output from the first one instead of the actual one.

How reproducible:

Always

Steps to reproduce:

1. execute a workflow (observed on wait-or-error)

2. as expected: during the workflow execution and after its completion, the /v2/workflows/instances/:id response contains both progress or final data as expected.

3.  re-execute the same workflow

4. issue: during the execution (not sure about final state), the /instances/:id response contains final data of the previous execution no matter the workflow has already produced intermediate data (as by this step: https://github.com/parodos-dev/backstage-orchestrator-workflows/blob/main/workflows/wait-or-error.sw.yaml#L31 .
The actual data returned incorrectly conform this step instead: https://github.com/parodos-dev/backstage-orchestrator-workflows/blob/main/workflows/wait-or-error.sw.yaml#L50

When tracking it down, the
https://github.com/janus-idp/backstage-plugins/blob/main/plugins/orchestrator-backend/src/service/OrchestratorService.ts#L102

already returns this "stale" data for two different instanceIds.

Actual results:

Content of the workflowdata contains data of previous execution

Expected results:
Content of the workflowdata should be exclusive for a particular execution.
