Wrong datatype in docs for wal_summary_keep_time

Hi,
I was reviewing new changes, and found out that we now have
"wal_summary_keep_time" setting, but the docs
(https://www.postgresql.org/docs/devel/runtime-config-wal.html#RUNTIME-CONFIG-WAL-SUMMARIZATION)
say that it's boolean, while it is integer.

The fix is simple:
