Changes include:
- Cleaning up the apt cache by adding `rm -rf /var/lib/apt/lists/*`
after each package installation within the same RUN statement.
- Ensuring the Docker image size is minimized by removing unnecessary
files immediately after use.
These adjustments will result in a more space-efficient Docker image.
Adjusted the README to correctly enumerate all 24 languages supported by
the project. This change includes the addition of Hungarian (Magyar) and
Bulgarian (Български) to the list, based on the properties files located
in 'src/main/resources'.
