Implement automatic versioning and display in the application

- Added a step in the CI/CD pipeline to generate a version based on the branch and commit history.
- Updated Dockerfile to accept the application version as an argument.
- Modified the configuration to retrieve the application version from the environment variable.
- Created a new API endpoint to expose the application version.
- Added a new Svelte component to display the application version in the UI.
