Bug Report

Description

Bug Summary:
Rag/Web requests (#url..) have empty User-Agent header causing some web sites denying the request

Expected Behavior:
Either a fix User-Agent or random User-Agent to imitate a real browser

Note

langchain_community.WebBaseLoader class used to fetch web pages has support for generating fake user agents using fake_useragent package in default use case. Installing this package is enough to start generating user agents.
