Support for passing platform

[poplexity]

Similar to #500 it would be great to have feature parity with the CLI. The suggested workaround does work but is quite inconvenient, we have migrated one project to use bollard directly such that we could specify the platform when launching the container.

After looking at the other implementations, this could perhaps be a more general request. We could expose a lower level API, similar to withCreateCmdModifier in testcontainers-java, and that could be used to configure various options:

• platform
• CPU and memory limits for repeatable environments for performance
• runtimes, to enable GPU support like in the Ollama module
