Update .dockerignore and improve Gitea CI workflow

- Expanded `.dockerignore` to include additional build artifacts, OS files, test files, IDE files, logs, and docs.
- Enhanced Gitea CI workflow by integrating `docker/setup-buildx-action` and switching to `docker/build-push-action` with caching support.
