Optimize DockerfileBase for Improved Efficiency and Reduced Size

[PeterDaveHello]

This pull request includes three commits that collectively optimize the DockerfileBase. The changes are focused on improving the build process, reducing the Docker image size, and maintaining consistency across the Dockerfile commands. Optimize DockerfileBase for Image Efficiency

• Add the --no-cache-dir flag to pip install --upgrade pip to align with other pip installation commands, prevent caching, and reduce Docker image layer size.
• Move Tesseract-OCR files to '/usr/share/tesseract-ocr-original' to prevent redundant operations and improve the efficiency of the backup process.
• Clean the apt cache within the same RUN statement after package installations by including rm -rf /var/lib/apt/lists/*, ensuring a reduced Docker image size by avoiding the retention of transient package data.

These changes contribute to a more efficient build process and a minimized Docker image, aligning with best practices for Dockerfile maintenance and deployment.

Docker image size before and after the change, a little bit smaller:

REPOSITORY          TAG                 IMAGE ID       CREATED          SIZE
base                after               91bee49112b9   19 hours ago     1.58GB
base                before              767036aed57a   20 hours ago     1.64GB
