Add Python Path configuration and command to package.json

- Added a new configuration 'DevChat.PythonPath' in package.json.
- This configuration allows users to specify the location of the Python binary.
- Also added a new command 'DevChat.PythonPath' to the command palette.
- Updated commandsBase.ts to use the Python Path from the configuration.
- If the Python Path is not set in the configuration, it will use the default Python command.
- If the DevChat status is 'Missing required dependency: Python3', the status bar item will trigger the 'devchat.PythonPath' command.
