OpenAI errors not caught

[Timoeller]

Describe the bug
When using the openai API a lot, e.g. during experiments, I get a lot of errors that are not caught.

In the previous haystack version we caught all OpenAIError, now it is just the OpenAIRateLimitError, see https://github.com/deepset-ai/haystack/pull/4460/files#r1182887215

Error message
File "/opt/homebrew/Caskroom/miniforge/base/envs/haystack/lib/python3.9/site-packages/openai/api_requestor.py", line 527, in request_raw
raise error.Timeout("Request timed out: {}".format(e)) from e
openai.error.Timeout: Request timed out: HTTPSConnectionPool(host='api.openai.com', port=443): Read timed out. (read timeout=600)

Process finished with exit code 1

Expected behavior
since the openAI API is quite unstable I would love to catch those errors.
