Fix missing Docling Import in document_mobject.ipynb

[rockenman1234]

Hello!

I'm a Georgia Tech Student (and former OSPO Intern) - I'm very interested in this project, but I found a minor bug in the docling python notebook. The notebook appears to not properly download and install docling alongside mellea - I've added !uv pip install docling to fix the issue.

Thank you for your time! :-)

@rockenman1234 Thanks for catching this. We recently re-organized our dependency management and moved docling to an optional dependency group, but forgot to update the associated tutorials and examples.

Although your PR is a functional solution, the cleaner way that this is by selecting the optional docling dependency groups for installation during the mellea installation:

uv pip install mellea[docling]

Would you mind changing

    !uv pip install mellea -q
    !uv pip install docling

to

    !uv pip install mellea[docling]

in this PR, and testing that this works?

@avinash2692 or @KenOcheltree : We should do a sweep for similar issues. Do either of you have time to thoroughly review the docs and the examples for similar issues? Specifically:

• check the rest of the ipynb's for these issues
• check the other contents of the examples directory for similar issues (or I guess we could always assume mellea[all] for those).
• check the narrative around commands/scripts in the tutorial to ensure that we don't have similar problems elsewhere (e.g., m tune needs [hf] I think)?

If either of you can take this up, please self-assign.

@nrfulton Yes sir - all done!

My apologies - I missed that part in the ReadMe. I've updated the cell - and confirmed it also fixed the issue!

If you'd like, I can help out more by scanning & fixing more of the ipynb's for y'all.

Thank you again!

We'll never say no to extra help! If you have the spare cycles, please go ahead :) I'll merge this PR now and let you open a new one with additional fixes.

@nrfulton I'm always happy to help! 😃

It's not a problem at all - thank you for your time, I should be able to verify the notebooks before the weekend. This helps me out since I wanted to incorporate Mellea into my own Root Cause Analysis tool (already using Granite, BeeAI, and Docling).
