[bug] Parsed response incorrectly shows HTTP/1.1 when forcing HTTP/3

[chanhanzhan]

Describe the bug
When the "Force HTTP/3" option is enabled for sites that support HTTP/3, the actual HTTP/3 handshake completes successfully. However, the parsed response displayed in the application always incorrectly shows as HTTP/1.1.

To Reproduce
Steps to reproduce the behavior:

1. Visit any website that supports HTTP/3.
2. Enable the "Force HTTP/3 request" option.
3. Observe the protocol version in the parsed response (it incorrectly displays as HTTP/1.1 despite a successful HTTP/3 handshake).

Expected behavior
The parsed response should correctly display HTTP/3 as the protocol version when a successful HTTP/3 handshake occurs.
