google collab redirect typo

[itay-ct]

On the page
https://github.com/redis-developer/redis-ai-resources/blob/main/python-recipes/semantic-router/00_semantic_routing.ipynb
the "open in collab" button is redirecting to a wrong URL:
https://colab.research.google.com/github/redis-developer/redis-ai-resources/blob/main/python-recipes/semantic-router/00_semantic_router.ipynb

It should be:
https://colab.research.google.com/github/redis-developer/redis-ai-resources/blob/main/python-recipes/semantic-router/00_semantic_route**ing**.ipynb
