Thank you for updating the patch! The patch looks mostly good to me.
Here is one minor point:
In logical-replication.sgml there is another place we need to update
(in 29.13.2. Prepare for subscriber upgrades):
<listitem>
<para>
The new cluster must have
<link linkend="guc-max-replication-slots"><varname>max_replication_slots</varname></link>
configured to a value greater than or equal to the number of
subscriptions present in the old cluster.
</para>
</listitem>
</itemizedlist>
