BUG: --server-response doesn't show headers in HTTP/1.1 mode

Steps to reproduce:

bash> wget2 --no-http2-S https://www.google.com

HTTP/1.1 200 OK

Date: Sat, 06 Sep 2025 03:16:14 GMT

But,

bash> wget2 --http2-only -S https://www.google.com

HTTP/1.1 200 OK

Date: Sat, 06 Sep 2025 03:16:14 GMT

Content-Length: ...

Cache-Control: ..

Expires: ...

<All the rest>

The bug isn't specifically about these http2 flags, I just used them for illustration.
