Docling Parse modifies root logging level

[davidmezzetti]

Importing Docling as shown below causes the root logger to be set to INFO.

from docling.document_converter import DocumentConverter

The code that is doing this is from docling-parse:

https://github.com/docling-project/docling-parse/blob/main/docling_parse/pdf_parser.py#L29

This change added this logging:

It's best practice to let the developer determine their own default logging level.
