Feat: add gpt oss models to aws bedrock (#5122)

* feat: add OpenAI GPT-OSS models to AWS Bedrock

- Add openai.gpt-oss-20b-1:0 (21B parameters, optimized for lower latency)
- Add openai.gpt-oss-120b-1:0 (120B parameters, optimized for production use)

* fix: update GPT-OSS models pricing on AWS Bedrock

- gpt-oss-20b: /bin/zsh.07//bin/zsh.30 per 1M tokens (input/output)
- gpt-oss-120b: /bin/zsh.15//bin/zsh.60 per 1M tokens (input/output)
