Improve doc on parallel stream changes for Stream Abort message

Hi,

While adding parsing of logical replication to Wireshark[1], I've
found the Stream Abort description possibly misleading. Stream Abort
will have the Abort LSN and TS when parallel streaming is enabled.
However, the documentation only mentions "This field is available
since protocol version 4" which could be interpreted (at least, I've
interpreted it this way) as "this field will always present with
protocol version 4".

The attached patch adds a "(only present for parallel stream)" mention
to the Abort LSN and TS documentation, akin to what's done for
parallel transactions.

Regards,
Anthonin
