CI: Fix PEP8 E722 Error and Confirm No Other Common flake8 Errors in locale/

[arohanajit]

Description:

This PR addresses the PEP8 style error E722 by specifying the exception type in the except clause within the writejson function in grass_po_stats.py. Additionally, it confirms that no other common flake8 errors (E122, E128, E231, E401) are present in the codebase

Changes Made:

• Specified Exception Type:
  • Changed the bare except: to except OSError: to catch only OS-related exceptions.

Rationale:

• Exception Handling:
  • Specifying OSError in the except clause is appropriate because os.remove() can raise various OS-related exceptions such as FileNotFoundError or PermissionError. This avoids catching unintended exceptions and adheres to PEP8 guidelines.
