Colab link not working

Link in the following section doesn't work:

# Build a learned optimizer from scratch
Simple, self-contained, learned optimizer example that does not depend on the learned_optimization library: Open In Colab

The link goes like this [https://colab.research.google.com/github/google/learned_optimization/blob/main/docs/notebooks/no_dependency_learned_optimizer.ipynb.ipynb]. There's a trailing `.ipynb` that should not be there.
