[Bug/Feature Request]: Add OPENAI_BASE_URL Environment Variable Support for PR Testing

[ppppangu]

I'm unable to submit my PR because I don't have an official OpenAI API key, even though my changes could be properly tested with an API-compatible service.

Proposed Solution

Add support for an optional OPENAI_BASE_URL environment variable in the PR testing workflow that allows specifying alternative API endpoints.

Implementation Approach

1. Modify the testing configuration to check for OPENAI_BASE_URL
2. If present, use this URL as the base endpoint for API calls
3. If not present, default to the official OpenAI API endpoint

Benefits

• Lower barrier to contribution for developers without OpenAI API access
• Enable testing with compatible services
• Support contributors from regions with limited OpenAI access
• Maintain compatibility with existing workflows for those using official API keys
