Step package step execution uses wrong package path with multiple cloud regions

I could reproduce the problem in the latest build

What happened?

When you have a step package step (in this case Deploy a Bicep Template step) executing on multiple workers on behalf of cloud targets. All workers will use the same path to find the package. This causes failures as package acquisition has a different path for each worker.

Reproduction

1. Create 2 cloud region targets with 2 worker pools each with their own worker
2. Use a Deploy a Bicep Template step with a package fetched from GitHub
3. Run the deployment and see that 1 worker will attempt to find the package using the path of the other worker
