fix: allow build on macos via docker

[thoro]

Comprehensive Summary of your change

Add the option to define the platform inside the Makefile, it defaults to linux and the corresponding arch where the Makefile is executed. For macos M1+ that would be arm64 - this requires the arch binary.

This is only intended for testing builds on macos / arm and not for running harbor on mac as a hosting platform

Updated the spectral version to the newest version (6.11.1) which provides an arm64 image.

Issue being fixed

A similar approach helped me to build images on my Mac a few months ago. Recently I discovered that environment variable does a similar job.

DOCKER_DEFAULT_PLATFORM: linux/amd64

Tested only with gitlab runner on Mac.

This is definitely good to know, I wasn't aware about DOCKER_DEFAULT_PLATFORM.

But maybe being explicit about it isn't that bad.
