Support latest ORT Web dists via URL parameter ort=[version] (for test automation or debug purpose easier):

• Demos load ONNX Runtime Web versions based on https://github.com/microsoft/webnn-developer-preview/blob/main/assets/js/common_utils.js#L125C1-L131C3 with following default values
  • Fixed dev version for Stable Diffusion 1.5, SD Turbo, and Whisper Base
  • Test version for Segment Anything
• User can change versions of ONNX Runtime Web dists for Stable Diffusion 1.5, SD Turbo, Segment Anything and Whisper Base by adding ?ort=[version] or &ort=[version], which will override the default version
  • ort=1.19.0 or ort=1.20.0-dev.20240810-6ae7e02d34 // Specify exact stable or dev versions from npmjs.com/package/onnxruntime-web?activeTab=versions
  • ort=test // Internal WebNN EP of ORT Web dists, usually including the patches which are not included in latest dev version
  • ort=latest // Get latest dev version of ONNX Runtime Web @honry
