Use unique artifact name to upload logs on CI failure

[sea-bass]

There is an issue when CI fails, in that both the test and log results artifacts uploaded on failure had the same name!

Run actions/upload-artifact@v4
With the provided path, there will be [12](https://github.com/PickNikRobotics/generate_parameter_library/actions/runs/12634499926/job/35202363937#step:5:13)2 files uploaded
Artifact name is valid!
Root directory input is valid!
Error: Failed to CreateArtifact: Received non-retryable error: Failed request: (409) Conflict: an artifact with this name already exists on the workflow run

Hah, apparently the upload-artifact v4 has this problem: actions/upload-artifact#478

I'm rolling it back
Apparently there is an overwrite parameter
