Running EmbeddingGemma ONNX with Hugot

[kepae]

Enjoyed running the (quantized) ONNX port of EmbeddingGemma with Hugot today!

A few observations:

• DownloadOptions.ExternalDataPath is needed to load the weights for this model (and others depending on packaging). That wasn't clear to me at first, I might try to update some docs/code doc with that or an example.
• Unless I'm mistaken, all of the session creating primitives now require the idiomatic context, which means updating the docs a bit
  • WIP: Add context.Context to session initialization examples #126
