Add minimal Dockerfile with Python and uv for easy onboarding (#843)

This PR address issue #837 

**Description of changes**
This PR adds a minimal Dockerfile and accompanying README to help new
users get started with Dora quickly. The Dockerfile includes Python
3.12, Rust, uv package manager, and the latest Dora release, creating a
consistent environment for development without requiring complex setup.

**What problem does this solve?**
New users currently need to install multiple dependencies (Python, Rust,
etc.) to get started with Dora. This Docker setup simplifies onboarding
by providing a pre-configured environment that works across different
platforms.

**Implementation details**
1. Created a docker/minimal directory
2. Added a Dockerfile with all necessary dependencies
3. Included a comprehensive README with build and usage instructions
4. Optimized the Docker image size by using the slim Python base image
and cleaning up after installations
