This pull request performs a routine update of the python-librarian-generator Docker image to its latest version, ensuring the system uses the most current build. Concurrently, it modifies the .librarian/state.yaml file to include a last_generated_commit field, which will likely be used for better tracking of library generation status.

Code Review

This pull request updates the librarian generator image and adds a new last_generated_commit field to the .librarian/state.yaml configuration file. While the image update appears to be a routine dependency bump, the new field last_generated_commit is initialized with an empty string. I have added a review comment highlighting a potential issue where an empty string might not be a valid value for downstream processes expecting a commit hash, which could lead to failures.

[gemini-code-assist]

The new field last_generated_commit is being initialized with an empty string. This could cause issues if downstream tooling expects a valid commit SHA. An empty string is not a valid commit SHA and may lead to processing errors. If a valid commit is not yet available, it might be better to omit this key if the schema allows it, to prevent potential failures.
