v1.6.0

feat: Add `response_completion_timeout` support @jwadolowski (#159)

## what

• Add support for response_completion_timeout argument (announced by AWS in July 2025 and implemented in the 6.13.0 version of the AWS provider)
• Bump the minimum provider version to >= 6.13.0 (it was incorrect anyway, e.g. grpc_config block needs 5.83.0 or newer)

why

Allows configuring response_completion_timeout for CloudFront origins.
