Release Python Workflow - Fix logic

[vgrassia]

📔 Objective

This PR updates the Release Python SDK workflow to fix some logic. The version in the setup job was being echoed to GITHUB_ENV instead of GITHUB_OUTPUT. The downloaded artifacts were all in separate directories, so I moved them all to a single directory to allow them to be uploaded to the GitHub release draft.
