chore: Update GitHub Actions for cross-platform Docker builds on PRs

- Implemented a new GitHub Actions workflow, `pr-check`, for automated Docker image builds on the `master` and `main` branches
- Configured QEMU, Docker Buildx, and Docker Hub authentication within the CI/CD pipeline
- Introduced Docker image builds with cache for improved build performance and reliability
- Established a workflow for pushing built Docker images to Docker Hub
