Added Github Actions for testing PRs for Docker Builds (Issue #83)

[Sak1012]

This pull request introduces a new GitHub Actions workflow (docker-pr.yml) to automate the building of Docker images for the eventyay-tickets project. The workflow is triggered whenever a pull request is opened or updated targeting the development or main branches. Additionally, it checks and installs Python dependencies before building the Docker image.
