I'd like to disable CondaPkg and use python in manually created .venv
Describe the solution you'd like
add meta config JULIA_PYTHONCALL_EXE=@venv that would load .venv/bin/python or .venv/Scripts/python.exe (on windows).
The folder .venv is at the same folder with (Julia)Project.toml just like .CondaPkg
Additional context
Now we have @CondaPkg (default), and @PyCall, I'd like to add @venv to simplify configuration.
