In Windows, 'os.rename' raises FileExistsError for overwrite

[Laoraid]

Describe the bug
Visit https://docs.python.org/3/library/os.html#os.rename
Overwriting files in Windows raises FileExistsError.(__main__.py line 326)
According to the document, I think it would be better to use replace() for cross-platform.

To Reproduce
Steps to reproduce the behavior:

1. Setup directories and files in windows
2. Install pigar..
3. Run pigar..
4. See error..

Expected behavior
Overwrite requirements.txt.

Context (Environment)

• OS: Windows 11
• Version of Python: 3.11.5
• Version of pigar: 2.1.1
