Fix issue #46: feat: add pandoc installation to Dockerfile

This PR addresses the changes requested in issue #46

Thank you for adding the Dockerfile to the chat. Based on the changes we discussed and the content you've provided, I can see that the Dockerfile has indeed been updated to include the Pandoc installation.

The relevant change is in this line:

RUN apt-get update && apt-get install -y git pandoc && apt-get clean && rm -rf /var/lib/apt/lists/*

This line now installs both Git and Pandoc in a single RUN command, which is an efficient way to add the new dependency.

For the purpose of writing the pull request description, we don't need any additional files. The Dockerfile contains all the relevant changes we need to describe.

Is there anything specific you'd like me to elaborate on or any other aspects of the changes you want me to include in the pull request description?
