Doc: clarify behavior of boolean options in replication commands.
defGetBoolean() allows the "value" part of "option = value" syntax to be omitted, in which case it's taken as "true". This is acknowledged in our syntax summaries for relevant commands, but we don't seem to have documented the actual behavior anywhere. Do so for CREATE/ALTER PUBLICATION/SUBSCRIPTION. Use generic boilerplate text for this, with the idea that we can copy-and-paste it into other relevant reference pages, whenever someone gets around to that.
