[Feature Request]: Add dimensions parameter to AzureOpenAIEmbedding

[viraj19r]

Feature Description

Currently, the OpenAIEmbedding class supports a dimensions parameter to specify the embedding size, but the AzureOpenAIEmbedding class does not. It would be beneficial to have this option in AzureOpenAIEmbedding as well.

Example Use Case with OpenAIEmbedding:

from llama_index.embeddings.openai import OpenAIEmbedding

embed_model = OpenAIEmbedding(
    model="text-embedding-3-large",
    dimensions=512,
)

embeddings = embed_model.get_text_embedding(
    "Open AI new Embeddings models with different dimensions is awesome."
)
print(len(embeddings))
