dont automatically inject PYTHONSTARTUP (#24346)

Resolves https://github.com/microsoft/vscode-python/issues/24345 and
https://github.com/microsoft/vscode-python/issues/24290 and
https://github.com/microsoft/vscode-python/issues/24105
remove automatic injection from before so only thing that allows shell
integration to user for Python terminal REPL is the setting itself.
