### Description
Updates the ORT build for web documentation to include the training WASM
artifacts
### Motivation and Context
* We are adding training bindings for web
* [This PR](https://github.com/microsoft/onnxruntime/pull/16521)
extended the WASM API wrapper to include training, allowing for training
artifacts (`ort-training-wasm-simd.wasm` and
`ort-training-wasm-simd.js`) to be built, and was merged in last week
* [This PR](https://github.com/microsoft/onnxruntime/pull/17319) will
add the training artifacts to the web pipeline & updates the
pull-wasm-artifacts script to also pull training artifacts.
This PR should not be merged in until the [pipeline
PR](https://github.com/microsoft/onnxruntime/pull/17319) is merged.
