Motivation & Context

The context providers README lists AZURE_OPENAI_EMBEDDING_DEPLOYMENT_NAME as the embedding setting for azure_ai_foundry_memory.py, but the sample reads os.environ["AZURE_OPENAI_EMBEDDING_MODEL"] when it builds the memory store definition (and its own docstring says "Set AZURE_OPENAI_EMBEDDING_MODEL for the embedding model"). Following the README gives KeyError: 'AZURE_OPENAI_EMBEDDING_MODEL' before the memory store is created.

Description & Review Guide

• What are the major changes? Rename the variable in the azure_ai_foundry_memory.py prerequisites of python/samples/02-agents/context_providers/README.md to AZURE_OPENAI_EMBEDDING_MODEL.
• What is the impact of these changes? Documentation only; the sample and its behavior are unchanged.
• What do you want reviewers to focus on? azure_ai_foundry_memory.py line 58 (embedding_model=os.environ["AZURE_OPENAI_EMBEDDING_MODEL"]). The same name is also what azure_ai_search/search_context_semantic.py uses, so the README is now consistent across the context provider samples.

Related Issue

N/A - trivial change. A stale environment-variable name in one README line; the correction follows the variable the existing sample already reads, with no behavior change.
