python.terminal.executeInFileDir no longer uses "cd" to switch the working directory

Type: Bug

# Behaviour

With previous versions of vs code, whenever I ran a python file in a terminal, there clearly was a "cd" command running, which changed the working directory to the files' directory, when python.terminal.executeInFileDir was enabled.
Now, when I run a file and a new terminal gets launched, it correctly opens in the selected files' directory. However, when I manually cd into a different dir and try to re-run the script, the working directory is no longer changed

## Steps to reproduce:

1. Run a python file
2. Manually switch to a different folder with cd
3. Run the same python file again
4. The working directory stays at the one manually switched to.
