Subject: [PATCH v1] Update protocol docs to not hardcode 3.0 in StartupMessage

We now also have protocol version 3.2, but in the protocol documentation
for the StartupMessage we still hardcoded the number for version 3.0.
This makes the description more generic, so we don't need to update for
every future protocol bump.
