Feat: Support multi platform docker image builds

[OjusWiZard]

Proposed changes

Support building and pushing the docker image for multiple CPU architectures
Next, the agents' github workflows (like trader) should be updated to use these new options.

How did you decide to stop using the docker SDK?

[OjusWiZard]

@Adamantios the two major reasons are:

1. It doesn't support buildx yet
2. There was no way to pass multiple platform arguments in the same build call.

I am very very very happy about this, i am currently blocked to get 3.12 support by a couple of dependencies here.

Please see pr;

8ball030/auto_dev#538

AFAICT you guys relied on requests within a fork of valory-docker-compose and the forked repo you have is not oss so i couldnt verify, i believe by removing the dependency we will basically be able to upgrade much more easily
