docs: Add a new section and a table listing protocol versions

Move the discussion on protocol versions and version negotiation to a
new "Protocol versions" section. Add a table listing all the different
protocol versions, starting from the obsolete protocol version 2, and
the PostgreSQL versions that support each.
