Feat/go versioning (#6)

* Enhance Dockerfile to include versioning information in build tags and environment variables

* Log application version on startup

* Update GitHub Actions workflow to enhance Docker image tagging with versioning

* Add GIN_MODE build argument for debug mode in Makefile

* Add GIN_MODE build argument to Dockerfile for release mode

* Update GitHub Actions workflow to dynamically set CACHE_TO for Docker caching

* Update Docker workflow and Dockerfile to include date-based version tagging

* Refactor Dockerfile to use ARG for date-based Go version tagging

* Update Dockerfile and workflow to use DATE_TAG for versioning
