fix broken scripts

This PR fixes the following scripts:

1) Scripts that can be executed within the repo's scripts directory.
   Note that these are for development testing and are not intended
   to be exposed to the user.

   configure_invokeai.py - configuration
   dream.py              - the legacy CLI
   images2prompt.py      - legacy "dream prompt" retriever
   invoke-new.py         - new nodes-based CLI
   invoke.py             - the legacy CLI under another name
   make_models_markdown_table.py - a utility used during the release/doc process
   pypi_helper.py        - another utility used during the release process
   sd-metadata.py        - retrieve JSON-formatted metadata from a PNG file

2) Scripts that are installed by pip install. They get placed into the venv's
   PATH and are intended to be the official entry points:

   invokeai-node-cli      - new nodes-based CLI
   invokeai-node-web      - new nodes-based web server
   invokeai               - legacy CLI
   invokeai-configure     - install time configuration script
   invokeai-merge         - model merging script
   invokeai-ti            - textual inversion script
   invokeai-model-install - model installer
   invokeai-update        - update script
   invokeai-metadata"     - retrieve JSON-formatted metadata from PNG files
