docs: Improve the description of num_timed column in pg_stat_checkpointer.
The previous documentation stated that num_timed reflects the number of
scheduled checkpoints performed. However, checkpoints may be skipped
if the server has been idle, and num_timed counts both skipped and completed
checkpoints. This commit clarifies the description to make it clear that
the counter includes both skipped and completed checkpoints.
Back-patch to v17 where pg_stat_checkpointer was added.
