[ci] Add test for installation in multiple architectures

Users should be able to install the frequenz-sdk package in amd64 and arm64
systems. This commit adds a simple test to the CI to validate this.

The aforementioned test builds a multi-platform docker image with the
generated wheel package. If the image gets successfully generated, then
the test passes.
