Better artifacts handling

[bakhtin]

• Set Docket image Rust version for building the binary by parsing a version configured for the project. That is to avoid manually updating Docker images when the Rust version bumps
• Consume build artifacts directly from the Docker image that built it using --output flag. Previously, we used a separate step to create a dummy container just to copy the artifacts.
• Replace release stage in the Docker image since we don't publish Docker images
