feat: add OpenAI gpt-oss models to Amazon Bedrock

- Added gpt-oss-20b-1:0 model (20B parameters, optimized for low latency)
- Added gpt-oss-120b-1:0 model (120B parameters, production-ready high-reasoning)
- Both models support 128K context window
- Configured with appropriate pricing estimates

Fixes #6752
