Incorrect parameter

[martinohanlon]

This function:

https://github.com/neo4j-graphacademy/llm-vectors-unstructured/blob/main/llm-vectors-unstructured/solutions/build_graph.py#L24

# tag::get_embedding[]
def get_embedding(llm, text):
    response = llm.embeddings.create(
            input=chunk.page_content,
            model="text-embedding-ada-002"
        )
    return response.data[0].embedding
# end::get_embedding[]

... doesn't use the text parameter passed to it. It still works as chunk is globally defined, but it should be changed.
