fix: update Docker workflow to build PAM plugin for linux/amd64 architecture

- Modified the PAM plugin build process to compile specifically for linux/amd64, addressing cross-compilation complexities.
- Added separate handling for the PAM plugin in the asset copying step to ensure it is correctly placed in the Docker assets directory.
- Removed unnecessary build targets for other architectures, streamlining the workflow.
