Re: Make pgoutput documentation easier to find

I applied the batch and built the html docs. I tested that all hyperlinks worked for me.

There are a few nit comments about wording:

diff --git a/doc/src/sgml/logicaldecoding.sgml b/doc/src/sgml/logicaldecoding.sgml

+ <xref linkend="test-decoding"/>. You can also write custom output plugins

nit: "write" -> "develop"

+ Protocol version. Currently versions <literal>1</literal>, <literal>2</literal>,

"Protocol version." -> "Specifies the protocol version."

+ Comma-separated list of publication names for which to subscribe
+ (receive changes). The individual publication names are treated

A comma-separated list of publication names to subscribe to. The individual publication names are treated

+ Boolean option to use binary transfer mode. Binary mode is faster

nit: "use" -> "enable", as other places all use "enable"

diff --git a/doc/src/sgml/protocol.sgml b/doc/src/sgml/protocol.sgml

+ The <literal>START_REPLICATION</literal> command allows us to
+ pass options to the logical decoding output plugin associated with
+ the replication slot specified in the command.
+ See <xref linkend="logicaldecoding-pgoutput-options"/> for options
+ that are accepted by the standard (<literal>pgoutput</literal>) plugin.

nit: The START_REPLICATION command can pass options to the logical decoding output plugin associated with the specified replication slot. See Section 47.6.1.1 for the options supported by the standard (pgoutput) plugin.
