Bug Fix: Update hub.py to fix NoneType error (#33315)

Browse Source 
* Bug Fix: Update hub.py

Bug:
TypeError: argument of type 'NoneType' is not iterable

Analysis:
The error `TypeError: argument of type 'NoneType' is not iterable` suggests that `model_card.data.tags` is `None`, and the code is trying to iterate through it using `not in`.

Fix:

1. **Check if `model_card.data.tags` is `None` before the loop**:
   Since you're checking the variable `tags` before the loop, you should also ensure that `model_card.data.tags` is not `None`. You can do this by initializing `model_card.data.tags` to an empty list if it's `None`.

2. **Updated code**:
   Add a check and initialize the `tags` if it is `None` before proceeding with the iteration.

This way, if `model_card.data.tags` is `None`, it gets converted to an empty list before checking the contents. This prevents the `TypeError`.
