add settings.toml to the rendered screenshots if needed.

Also fixed a bug with code file icon showing empty file for some files that should have been the code icon.

Whether to render settings.toml or not is determined by whether any of a certain list of libraries are used by the project. The current list is:

LIBRARIES_THAT_REQUIRE_SETTINGS = [
    "adafruit_requests.mpy",
    "adafruit_esp32spi",
    "adafruit_minimqtt",
    "adafruit_portalbase",
    "adafruit_azureiot",
]

Here's one example of the new screenshot with settings.toml included

If the project doesn't have one of the specified libraries used it will render the same as it would have previously. Here is one without settings.toml:
