Fix uncaught exception in Google retrieval

File "/home/winston/.local/lib/python3.10/site-packages/gp _researcher/retrievers/google/google.py", line 83, in searc

"body": result["snippet"],
KeyError: 'snippet'
Error! : HTTPSConnectionPool(host='zyk.bjhd.gov.cn', port=44
3): Read timed out. (read timeout=4)

gpt-researcher crashes if a Google search result doesn't contain a snippet (which happens on errors such as read timeout)

@assafelovic sorry for all the PRs, just another bug fix. gpt-r completely crashes when scraping certain websites with Google.

@winsonluk the opposite! Please create as many PRs as you think are necessary, love your work! Thanks

@assafelovic thank you! just curious, do you know when the next package release to pip will be?
