Docs/damon: update outdated term 'regions update interval'
Before DAMON is merged in the mainline, the concept of 'regions update interval' has generalized to be used as the time interval for update of any monitoring operations related data structure, but the document has not updated properly. This commit updates the document for better consistency.
