Improved models are now available for the following features

## Change Improved models are now available for the following features: * Text detection and documentation text detection (OCR) * Web detection * Logo detection * Object localization Specify `"builtin/latest"` in the `model` field of a `Feature` object to use the new models. We'll support both the current model and the new model the next 90 days. After 90 days, the new models will become the default. The current models can still be accessed by specifying `"builtin/legacy"` for an additional 90 days before they are deprecated.
