Debugging Python code in a venv in WSL always takes two tries

Testing #859

I'm using an Ubuntu WSL instance with pwsh as the default terminal profile.
When I debug a file with Python and with the Python Environments extension enabled, the terminal first runs the debugger commands, and then it cancels that command and runs the venv enablement command. As a result, the debugger fails to launch. On the second attempt, the debugger successfully runs the file because it is not intercepted by the venv enablement command. It successfully hits the breakpoint.
