songtianlun 2c72e96977 feat: switch to using official ruby slim image
Update the Dockerfile to use the official ruby slim image, rather than a custom image. This reduces the Docker image size and improves build times.

- Update the base build and development images to use the official ruby slim image
- Remove redundant arguments in the build and development stages

Using the official ruby slim image simplifies the build process and reduces the image size, resulting in faster build times and a more maintainable Dockerfile.
