Code Review

This pull request updates the apache_beam dependency to version 2.66.0. While this is a routine update, it requires a corresponding change in the project's Dockerfile to keep the Beam SDK version consistent. I've added a comment highlighting this necessary change to prevent potential runtime failures.

[gemini-code-assist]

Updating apache_beam to v2.66.0 here will cause a version mismatch with the Beam SDK used in the Dockerfile, which can lead to runtime failures for the Dataflow job.

The Dockerfile for this sample hardcodes the Beam SDK version at line 33:

# File: dataflow/gemma-flex-template/Dockerfile
...
32: # The Beam version should match the version specified in requirements.txt
33: COPY --from=apache/beam_python3.10_sdk:2.62.0 /opt/apache/beam /opt/apache/beam

As the comment on line 32 states, this version should match the one in requirements.txt.

To fix this, please update the Dockerfile to use a matching 2.66.0 image tag. This change is required in a separate file, but is a direct consequence of this dependency update.
