File vectorstores/sqlitevec.py is missing from the release package

Checked other resources

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

Example Code

from langchain_community.vectorstores import SQLiteVec

Error Message and Stack Trace (if applicable)

from langchain_community.vectorstores import SQLiteVec

E ImportError: cannot import name 'SQLiteVec' from 'langchain_community.vectorstores' (/opt/miniconda3/envs/rag_env/lib/python3.11/site-packages/langchain_community/vectorstores/init.py)

Description

I installed latest langchain_community and I get import error when trying to import SQLiteVec. I downloaded and unpack package manually and i don't see vectorstores/sqlitevec.py. Probably it was not added to the packaging spec
