chore: Fix for Incorrect Object Passing and Loop Control

[mdqst]

Description

I noticed a couple of issues in the script:

1. The function fix_unreachable_pub_warning was receiving m (part of the warning) instead of the full warning object, which caused unexpected behavior. I fixed this by passing the correct object.
2. The script was using return to exit the loop when the code wasn't in the current workspace. I replaced it with continue to ensure the loop processes all warnings as intended.
