fix: update shoprenter-proxy to use HTTP/1.1 instead of HTTP/1.0 #55

- Changed HTTP version from 1.0 to 1.1 to match curl command that works
- This resolves TLS close_notify connection errors
- Updated function name from makeHttp10Request to makeHttp11Request
- Updated all related log messages and comments
