Subject: [PATCH] doc: replace alpn with protocol in quic.md

The code was refactored in commit 062ae6f3cb5 to use 'protocol'
instead of 'alpn' for the ALPN protocol identifier option.
However, the documentation was not updated to reflect this change.

This commit updates the documentation to match the actual
implementation:
- Removes the non-functional 'alpn' option from SessionOptions
- Adds the 'protocol' option with proper description
- Updates example code to use 'protocol' instead of 'alpn'
- Updates OnHandshakeCallback parameter from 'alpn' to 'protocol'
