06f6c49e - Improve `llm_chain.ipynb` and `getting_started.ipynb` for chains docs (#3380)

Improve `llm_chain.ipynb` and `getting_started.ipynb` for chains docs (#3380) My attempt at improving the `Chain`'s `Getting Started` docs and `LLMChain` docs. Might need some proof-reading as English is not my first language. In LLM examples, I replaced the example use case when a simpler one (shorter LLM output) to reduce cognitive load.
