Virtual environment still in interpreter list after being deleted.

[ericsnowcurrently]

(using the latest nightly build of the extension)

The extension notices when I've created a new virtual environment. It should also notice when I've deleted that virtual environment (and forget it). Currently it does not.

steps:

1. verify there are only "system" Pythons in the interpreter list (click on Python version in status bar to see available interpreters)
2. in the workspace root, run python3 -m venv .venv
3. verify the new virtual environment is in the interpreter list
4. delete the ".venv" directory created in step 2
5. check the interpreter list to see if the virtual environment is still there (it still is)

Closing as this happens because VSCode watcher doesn't fire event as designed.
