[Feature]: TestContainer per arch to run go tests in custom environments

[go-dockly]

Problem

It would be a killer feature if we could spin up a go test container dedicated to running golang tests on different platforms.

Solution

Cherry on the cake if one could also define arch eg amd64 on arm [Rosetta emulation on macOS]

Benefit

It's obvious?

Alternatives

Not sure what would be as convenient as using go test containers for what the name suggests ;)

Would you like to help contributing this feature?

Maybe

Hey @go-dockly thanks for opening this feature request. I'd like to know more about this: do you envision a way to create a container in a given platform and put the workspace into it to run the tests?

Please consider that testcontainers is a developer-friendly wrapper of the Docker package, so I think what you propose could be done as a separate project (maybe a CLI) that uses tc-go as runtime, so you run your binary, say gotc (go testcontainers) like this:

gotc --platform=amd64 --goversion=1.23.1

And it would use tc-go to spin up a container in the desired flavour (go version + platform), then mount the current workspace into the container, and finally run the tests.

Does this resonate to you?
