Type: Bug

Behaviour

Running a terminal with both ms-python.python and ms-python.debugpy extensions contributing to the terminal environment has conflicts - i.e. cannot run debugpy becuase it's not in the path if it is not the last environment override (therefore there may be some randomness for reproducing depending on the order of these overrides).

Steps to reproduce:

1. Open a project with a venv
2. Ensure both the ms-python.python and ms-python.debugpy extensions are present
3. Ensure python.terminal.shellIntegration.enabled is true
4. Open / restart the terminal
5. Start a Python shell. I expect the option to open in Native REPL to be there, but it is not
6. Type debugpy .It may not be in the path despite the message from the terminal stating you can run it

Diagnostic data

Below is the changes to the terminal environment reported by VS Code. The ms-python.python and ms-python.debugpy overwrite each other. The $PATH variable will depend on the order of the changes, which is not configurable.
