Move embedding model description

Move embedding model description to a better place.

AS IS	TO BE

I put it in that position because CODE_BLOCK_3 is where you need that reference documentation. General idea was to keep documentation closest to where it's needed.

I see. That makes sense for providing the link to the reference documentation before the actual usage.

There was feedback that it would be beneficial to add a link to the embedding model (CLIP) where it is first introduced in the code, so that developers can understand what clip-ViT-B-32 means. What do you think about providing a general link to the model immediately after the Step 3 header, while keeping the reference link in place as is?

@bohyunjung Can do! I will add this in a separate PR with a few other changes. Closing this one.
