Added jupyter notebook for Geospatial Blog

[philippkahr]

Hi,

this should add the geospatial Jupyter Notebook for the accompanying blog post.

Hi there,

Theres an issue rendering the notebook (https://github.com/elastic/elasticsearch-labs/blob/c9d54687840cac94f94dffa5ac4e4e76a9c7f2ce/notebooks/search/09-geospatial-search.ipynb) - looks like you have images in the notebook that doesn't exist.

Also as this is for content for blog, could you add it in the supporting-blog-content folder instead please?

@philippkahr I think you've got a formatting issue still on the notebook as it's still not building:

:11: SyntaxWarning: invalid escape sequence '.' :11: SyntaxWarning: invalid escape sequence '.' :11: SyntaxWarning: invalid escape sequence '.' error: cannot format supporting-blog-content/geospatial-llm/09-geospatial-search.ipynb: Cannot parse: 37:46: print(f"Distance between AirBnB and {hit["_source"]["name"]}: {hit["sort"][0]} km")
