backward compatibily with venv

Feature Description

It should have good compatibility with the old venv, so that if I start the virtual environment it loads all the libraries it installs with pdm. Apparently, this is the case, but when I run something with the virtual environment or try to use pyinstaller, it doesn't recognize the libraries.

Problem and Solution

The solution is for the virtual environment to be easily recognizable by the previous one.
