This pull request introduces a new GitHub Actions workflow to build and deploy Docker containers for Rust and Next.js projects. The workflow includes steps for building, testing, and pushing Docker images to the GitHub Container Registry.

GitHub Issue: [Closes] #82

Changes

• Added a new Github Actions workflow configuration file .github/workflows/build_and_deploy_containers.yml to automate the build and deployment process for feature branches and pull requests to the main branch.
• Defined two main jobs: build_test_run for building and testing the project, and build_and_push_docker for building and pushing Docker images. The latter job depends on the successful completion of the former.
• Configured steps to checkout the repository, install the Rust toolchain, use cached dependencies, install seaORM CLI, build the project, and run tests.
• Configured steps to checkout the repository, log in to the GitHub Container Registry, set up Docker Buildx, cache Docker layers, and build and push Docker images for both the Rust backend and the Next.js frontend.
• Implemented a caching mechanism for Docker layers to optimize the build process, including steps## Description

Testing Strategy

• Manually use the workflow_dispatch to iterate and view any errors from the workflow run.

Concerns

• Managing environment variables, and secrets can be improved upon in the future.
