Issue: langchain-chroma== 0.1.4   method get_by_ids is listed in documentation BUT I am getting NotImplementedError
Labels: Ɑ: vector store

### Checked other resources

- [X] I added a very descriptive title to this issue.
- [X] I searched the LangChain documentation with the integrated search.
- [X] I used the GitHub search to find a similar question and didn't find it.
- [X] I am sure that this is a bug in LangChain rather than my code.
- [X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

### Example Code

```
#----------------
# HuggingFace embedding  (no issue)
from langchain_huggingface import HuggingFaceEmbeddings
embeddings = HuggingFaceEmbeddings(model="sentence-transformers/all-mpnet-base-v2")


#----------------
# create langchain-chroma persistent client with collection name 'example_collection;  (no issue)
from langchain_chroma import Chroma

vector_store = Chroma(
    collection_name="example_collection",   # collection is "table" in vectore store 
    embedding_function=hf,    # hf is huggingface embeddings derived  from the previous step 
    persist_directory="./vectorstore/chroma_langchain_db",  # Where to save data locally, remove if not necessary
)


#----------------
# add at least one document into  vector collection (no issue)
from uuid import uuid4
from langchain_core.documents import Document

document_1 = Document(
    page_content="I had chocolate chip pancakes and scrambled eggs for breakfast this morning.",
    metadata={"source": "tweet"},
    id=1,
)

documents = [
    document_1,
]

uuids = [str(uuid4()) for _ in range(len(documents))]
vector_store.add_documents(documents=documents, ids=uuids)



#----------------  ERROR ENCOUNTERED when running get_by_ids 
# attempt to run get_by_Ids yields NotImplementedError
vector_store.get_by_ids(['6314982d-455f-47cc-bf97-6e5324f6af62'])

```

### Description

I am just trying to run the vector_store method `get_by_ids`  - it is listed as one of the available methods in [here](https://python.langchain.com/api_reference/chroma/vectorstores/langchain_chroma.vectorstores.Chroma.html)
