[Bug]: httpx.ConnectTimeout errors when using GithubRepositoryReader

[rchan26]

Bug Description

I'm currently using the GithubRepositoryReader with llama-hub version 0.0.66 to read documents from a private Github repo which has a lot of markdown documents in. I'm finding that I'm often getting httpx.ConnectTimeout errors and it seems like the default timeout for httpx is only 5 seconds (https://www.python-httpx.org/advanced/#timeout-configuration).

Is there any way which we can set the timeout easily?

Version

llama-index: 0.9.25.post1, llama-hub: 0.0.66

Steps to Reproduce

I'm only getting this in times where my connection is poor. But I'm not 100% sure if that is the cause of this issue.
