The error message indicated a version mismatch between the installed ICU library and the version supported by PyICU, as well as a C++ compiler version issue.
Steps to Reproduce
Clone the gcd-django-docker repository.
Run docker-compose up.

Proposed Solution
The error points to a version incompatibility between the PyICU library (which supports ICU up to version 74) and the ICU library present in the container (version 76.1). The C++ compiler also appears to be too old to support features required by the ICU version.
Might be resolved by:
Downgrading the ICU library in the Docker image to a version compatible with PyICU (e.g., version 74 or earlier).
Upgrading the PyICU version in the requirements.txt to one that supports ICU 76.1 or newer.
Updating the base Docker image to a version that includes a C++ compiler compatible with the current setup.
