wine 5.13 does not allow anymore to install pip using get-pip.py:

cd /tmp
wget https://www.python.org/ftp/python/3.8.5/python-3.8.5-embed-amd64.zip
unzip python-3.8.5-embed-amd64.zip
wget https://bootstrap.pypa.io/get-pip.py
wine python.exe get-pip.py

PermissionError: [WinError 5] Access denied:
'C:\users\devel\Temp\tmph5r7fzpp\pip.zip\pip\_vendor\certifi\cacert.pem'

this is a regression as wine 5.10 is ok
