Update Dockerfile to include additional TypeScript definition files

- Amend the Dockerfile to copy `next-env.d.ts` and `svgr.d.ts` files along with the existing `next.config.js` and `tsconfig.json`. This ensures that all necessary TypeScript definition files are available in the Docker image, supporting proper type-checking and configuration during the build process.
- These changes aim to enhance build stability and maintain consistency across development and production environments by ensuring all relevant configuration files are included in the Docker build context.

This adjustment ensures that the Docker environment mirrors the local development setup more closely, potentially reducing issues related to environment discrepancies.
