Add Support for ARM64 Architecture in Docker Image

[stepanov1997]

I would like to propose adding support for the ARM64 architecture to the Docker image of the BigQuery emulator. With the increasing popularity and usage of ARM64-based systems, especially with the advent of ARM-based processors in both servers and personal computing devices, it is crucial for the Docker image to be compatible with these architectures.

Adding ARM64 support to the Docker image will:

•	Enhance the emulator’s usability on a broader range of hardware.
•	Enable developers using ARM64-based systems to leverage the BigQuery emulator Docker image without the need for workarounds or additional virtualization.
•	Promote greater flexibility and inclusivity for developers working on various hardware configurations.

I believe this enhancement will greatly benefit the community and align with the ongoing industry trend towards ARM64 adoption. Thank you for considering this request.

Unsure if this will help, but you should be able to run the emulator on a ARM64 based ( I tested on a M2 mac ) by passing in the platform flag to the docker run command.
docker run --platform linux/x86_64 -it ghcr.io/goccy/bigquery-emulator:latest --project=test-project

It's mentioned at the end of How to start the standalone server section just in case if you missed it.

I managed to build an ARM64 image locally, it needed 3 changes:

1. build go-zetasql as ARM64 (no changes needed)
2. update debian:bullseye to debian:bookworm in the emulator stage in the Dockerfile (here)
3. comment out this bit in the Makefile (here):

ifneq ($(UNAME_OS),Darwin)
	STATIC_LINK_FLAG := -linkmode external -extldflags "-static"
