Conda entries duplicate after installing python

Testing #18731

For this to work, ensure that your global python is a python.org install.

We tried debugging but could no longer reproduce this issue where that entry is duplicated after install 🤷‍♂️ But another bug in that screenshot is that the executable install inside the env failed, and is still pointing to an executable outside environment. That issue should be solved with #18767.
