Google Generative AI "Temperature" value range is limited to 1, while the API allows up to 2

[shaiger]

The problem

It makes sense that the recommended value would be 1 in case the Control option is selected. But when there is no need in control, there is no reason to limit this value. In addition, It would be great to be able to experiment with the impact of larger Temperature values even when control is permitted.
Another awesome addition would be to be able to override the preset value when explicitly calling "Conversation.Process" in an automation, but this already falls under a feature request rather than a bug.
