Currently attempting to run the chart on an ARM64 Kubernetes cluster (like an M1 MacBook) will fail with the default configs. This is because our ghcr.io/airflow-helm/pgbouncer image fails when run under emulation.

We need to do the following to have pgbouncer work natively on ARM64:

1. Build the ./images/pgbouncer/Dockerfile locally on an ARM64 device and attempt to use it with the chart.
2. (Adjust the Dockerfile until this works)
3. Update the buildx workflow to target linux/amd64 AND linux/arm64
