chore: update model alias to nemotron-speech-streaming-en-0.6b across all samples

Update the model name from 'nemotron' to 'nemotron-speech-streaming-en-0.6b'
in all 5 language samples (JS, C#, Python, Rust, C++). Also align the JS
sample with the reference at ruiren/build-js-sdk-packaging (appName, banner).
