Description

Several public methods in InMemoryVectorStore
(libs/core/langchain_core/vectorstores/in_memory.py) are missing
docstrings while the parent VectorStore class documents them fully.

Methods affected:

• embeddings
• delete / adelete
• add_documents / aadd_documents
• similarity_search / asimilarity_search
• similarity_search_with_score / asimilarity_search_with_score
• similarity_search_by_vector / asimilarity_search_by_vector
• max_marginal_relevance_search_by_vector
• max_marginal_relevance_search / amax_marginal_relevance_search
• from_texts / afrom_texts

I'd like to fix this by opening a PR against langchain-ai/langchain
adding docstrings consistent with the style used in the parent
VectorStore class.
