[RHOAIENG-6802] Fix to show all artifacts in pipeline topology view

[jeff-phillips-18]

Closes: RHOAIENG-6802

Description

Artifacts with the same name created by different tasks were being thrown out due to duplicate IDs. Update the generation of the artifact nodes to create a unique ID for the artifact based on its parent task's ID.

How Has This Been Tested?

Verified locally that the artifact nodes show up correctly with the correct dependencies.
