Fixing issue #678 -> pynb for image classification using vision transformer pretrained on ImageNet.

[ShreyasJoshi7]

Description

I have added a notebook which contains inference code for image classification using vision transformer pretrained on IamgeNet. The code performs the following tasks:

1. downloads the checkpoint (which can be downloaded and used to fintune the model on aditional classes).
2. downloads a test image.
3. downloads the json file of ImageNet classes.

This notebook solves the issue #678 which requires an image classifier which uses transformer.

Just a heads up, you can review these notebook changes with GitNotebooks too: https://gitnotebooks.com/microsoft/computervision-recipes/pull/690

I think it offers some advantages over what you're currently using.
