Steps to reproduce

Make sure the AI Image Descriptions feature is turned on and launch NVDA. You will get this in the log.
NVDA initialized
INFO - _localCaptioner.captioner.VitGpt2ImageCaptioner._loadVocab (07:42:08.773) - MainThread (18124):
Successfully loaded vocabulary with 50257 tokens

Actual behavior

The AI Image Descriptions takes about 2 seconds to load on my hardware which is high end so it will only take more time on slower hardware.

Expected behavior

I would expect this to be loaded in the background so as not to impact NVDA startup time. Pressing the key to describe the image could say something like "AI Image Descriptions still loading" if the user pressed it while the loading" was still taking place in the background. If this is already planned then I'm sorry for the report, but I'd rather be safe than sorry.
