Fixes: Incomplete Fix for Stage Bucket URL Handling -> Relates Change (PR #2342)

Description

Fixes the issue #3011

• Currently, the logic only checks whether the stage_bucket_url consists of {scheme} and {netloc} and assumes an empty path (e.g., az://my_net_loc/). This works fine for URLs without a subfolder. However, if the user specifies a subfolder (e.g., az://my_net_loc/subfolder/), the current implementation causes a "file not found" error when accessing Azure.
  This change/pull request resolves the problem and improves the usability.
