`PermissionError` on Windows when deleting empty log file

[Rodrigo Girão Serrão]

On Windows 10 64 bit Python 3.9, running tryceratops displays the violations that tryceratops finds, but then a permission error is thrown when the program tries to delete the .tryceratops-errors.log empty file.

The full traceback follows:

tryceratops was invoked with the command python -m tryceratops my_code_file.py.

Nice! Thank you for reporting.
It's curious that Windows allows creating, but not delete ha

I believe tryceratops should try to delete, but ignore the exception in case it fails. What do you think?
