fix(deploy): improve Caddyfile check for windwiderstand domain

- Updated the grep command in the deployment workflow to use a regex pattern for better matching of the windwiderstand.de domain in the Caddyfile.
- This change ensures that the domain is correctly identified even with variations in whitespace or formatting.
