No ARM64 support for Fabric images

[arturmartins]

I just learned that there is no ARM64 support:

firefly-cli/internal/blockchain/fabric/fabric_provider.go

Line 621 in 9c8b5dd

return "linux/amd64"

It would be important to have a document explaining why. Furthermore, it would be greatly appreciated if there was an explanation of how it could be done locally (build your own images).

I think it was the case that Fabric did not have ARM64 images but it seems that it has changed! https://lists.hyperledger.org/g/fabric/topic/96571575?p=%2C%2C%2C20%2C0%2C0%2C0%3A%3A%2C%2C%2C0%2C0%2C0%2C96571575

This would be a great contribution to make, marking as good first issue 😃

For anyone looking at contributing a fix for this , I've just come across the same problem for Tessera in this PR #315 and most of the hard work can be taken from that PR.

This is a great first issue for anyone to pick up!

@dwertent found out that actually the v1.3.1 FF already has bumped the version to 2.5 of Fabric which has an ARM64 image in DockerHub, so the issue is obsolete
