[improvement](compaction) reduce tablet skip compaction time (#44273) (…

…#44791)

pick master #44273

The time for tablet skip compaction is 120 seconds, which is too long.
In the scenario of high-frequency import (mow), it leads to a high
compaction score. Therefore, reducing the skip time to 10 seconds is
necessary.
