PG15 beta1 fix pg_stat_recovery_prefetch view manual

[Shinoda, Noriyoshi (PN Japan FSIP)]

Hi hackers,
Thanks to all the developers. The attached patch updates the manual for the 
pg_stat_recovery_prefetch view.
The current pg_stat_recovery_prefetch view definition is missing the 
stats_reset column. The attached patch adds information in the stats_reset 
column.
