Add Dockerfile and Docker Compose Support for Selected Databases

We want to add support for generating a `Dockerfile` and `docker-compose.yml` file along with the project. This should allow users to easily set up containerized environments, including support for a database of their choice (MongoDB, PostgreSQL, MySQL, SQLServer).

**Tasks:**
- Add a feature to the generator that creates a `Dockerfile` with the latest Node LTS.
- Create a `docker-compose.yml` template that includes configurations for the selected database (e.g., MongoDB, PostgreSQL, MySQL, SQLServer).
- Ensure that the generated Docker setup works out of the box with the project.
- Test the Docker setup for each database option.
- Update documentation to include instructions on using Docker with the generated projects.

**Expected Outcome:**
Generated Express.js projects should include a working `Dockerfile` and `docker-compose.yml` for easy setup with Docker, using the latest Node LTS and a selected database.
