Bob Merkus 8e3e532e7d docs: ollama doc update (toolcalling, install, notebook examples) (#25549)
The new `langchain-ollama` package seems pretty well implemented, but I
noticed the docs were still outdated so I decided to fix em up a bit.

- Llama3.1 was release on 23rd of July;
https://ai.meta.com/blog/meta-llama-3-1/
- Ollama supports tool calling since 25th of July;
https://ollama.com/blog/tool-support
- LangChain Ollama partner package was released 1st of august;
https://pypi.org/project/langchain-ollama/

**Problem**: Docs note langchain-community instead of langchain-ollama

**Solution**: Update docs to
https://python.langchain.com/v0.2/docs/integrations/chat/ollama/


**Problem**: OllamaFunctions is deprecated, as noted on
[Integrations](https://python.langchain.com/v0.2/docs/integrations/chat/ollama_functions/):
This was an experimental wrapper that attempts to bolt-on tool calling
support to models that do not natively support it. The [primary Ollama
integration](https://python.langchain.com/v0.2/docs/integrations/chat/ollama/) now
supports tool calling, and should be used instead.

**Solution**: Delete old notebook from repo, update the existing one
with @tool decorator + pydantic examples to the notebook


**Problem**: Llama3.1 was released while llama3-groq-tool-call fine-tune
Is noted in notebooks.

**Solution**: update docs + notebooks to llama3.1 (which has improved
tool calling support)


**Problem**: Install instructions are incomplete, there is no
information to download a model and/or run the Ollama server

**Solution**: Add simple instructions to start the ollama service and
pull model (for toolcalling)
