commit 72041c63064b461e2eb9102f12c4fe217e9066dd
Author: David Goulet <dgoulet@xxxxxxxxxxxxxx>

    relay: Don't advertise HSv2 protocol version
    
    We removed HSIntro=3 and HSDir=1 that are v2 specific. Since 0.3.5.17,
    we do not support introducing or being a directory for onion service v2.
    
    Closes #40509
