PR checklist:

• Did you run ClangFormat ? N/A
• Did you separate headers to a different section in existing community code base ? N/A
• Did you surround proton: starts/ends for new code in existing community code base ? N/A

These changes should allow building Docker images on:

• arm64, in addition to:
• x86_64 (amd64)

The images can then be published to Timeplus' Docker Hub.
