Fix documentation for POSIX semaphores.
The documentation for POSIX semaphores is missing a reference to
max_wal_senders. This commit fixes that in the same way that
commit 4ebe51a5fb fixed the same issue in the documentation for
System V semaphores.

When using POSIX semaphores, the number of semaphores needed is the
same as for System V, that is one semaphore per allowed connection
(<xref linkend="guc-max-connections"/>), allowed autovacuum worker process
- (<xref linkend="guc-autovacuum-max-workers"/>) and allowed background
+ (<xref linkend="guc-autovacuum-max-workers"/>), allowed WAL sender process
+ (<xref linkend="guc-max-wal-senders"/>), and allowed background
process (<xref linkend="guc-max-worker-processes"/>).
On the platforms where this option is preferred, there is no specific
kernel limit on the number of POSIX semaphores.
