New https release is breaking openai sdk while intitiating Async client

[Alavi1412]

Confirm this is an issue with the Python library and not an underlying OpenAI API

• This is an issue with the Python library

Describe the bug

Recently, my codebase started to fail while initiating AsyncOpenAi. While debugging, I noticed AsyncOpenAI is using a version of httpx that accept keyword proxies but in the latest version (httpx 0.28.0), this keyword argument is removed from __init__.

To fix it, I manually limited installed httpx to use 0.27.2 which solves the problem but OpenAI SDK should have applied already that limitation on httpx allowed versions.

To Reproduce

1. Install openai v1.30.1 with latest version of httpx (0.28)
2. Create a new instance of AsyncOpenAI
3. You should see the error at the instance creation.
