Builds of MMO on arm64 MacOS fail

[aleskandro]

@lwan-wanglin noticed there might be some issue with building the operator image on top of an arm64 MacOS system with make docker-buildx and make docker-build.

This might be related to golang/go#57485

is this operator going to be made available for macos or only linux? that said, we should also think about windows in that case as well

Yeah, the issue here is about building it 'locally' (e.g., for dev purposes) from a MacOS workstation. We all use Fedora when developing it, but the linked issue might affect builds on MacOS systems based on arm64. We'd try on Windows systems too, if we have any.
