## Title

    [deepeval / Bedrock] TypeScript AmazonBedrockModel sends temperature:0 by default breaking OpenAI GPT models on Bedrock

## Body

    ## Observed symptom
    TypeScript AmazonBedrockModel sends temperature: 0 by default, so OpenAI GPT-6 Sol/Luna/Astra on Bedrock fail with 400
    
    Thanks for the TypeScript SDK and for the `temperature: null` escape hatch in `resolveTemperature()`. It made this easy to confirm.
    
    On main (86b6fb51), `new AmazonBedrockModel({ model: "us.openai.gpt-6-sol" })` sends `inferenceConfig: { temperature: 0 }` although no temperature was set. OpenAI GPT-6 Sol, Luna and Astra on Bedrock reject the temperature field on Converse at any value, including 1. So `generate()` and every metric using these models fail with a 400. Python's `AmazonBedrockModel` sends no temperature unless asked (#2151) and works with all three.
    
    ## Literal error text
