Update Docling to 1.20.0

[dolfim-ibm]

Why are these changes needed?

The Docling updates allow (among others)

• Support for Windows (Refs [Bug] unable to install release 0.2.1 on windows #644)
• Improved table results (e.g. identifying column headers)
• Use torch instead of onnx for all models

@sujee If you want to test if @dolfim-ibm's latest version of docling (1.20.0) works on a notebook that uses pdf2parquet on a Windows machine as part of your RAG example (assuming you have access to a native Windows machine!), you can try:
pip install --extra-index-url https://testpypi.python.org/pypi 'data-prep-toolkit-transforms[pdf2parquet]==0.2.2.dev1'
this version of docling is not in pypi's 0.2.2.dev1 and will be in the next release on pypi.
