Docs/mm/damon: fix spelling and grammar in monitoring_intervals_tuning_example.rst 

This patch fixes some spelling and grammar mistakes in the documentation,
improving the readability.

- multipled  -> multiplied
- idential   -> identical
- minuts     -> minutes
- efficieny  -> efficiency

"access temperature".  "Access temperature" is a metric representing the

access-hotness of a region.  It is calculated as a weighted sum of the access

frequency and the age of the region.  If the access frequency is 0 %, the

temperature is multipled by minus one.  That is, if a region is not accessed,

temperature is multiplied by minus one.  That is, if a region is not accessed,

it gets minus temperature and it gets lower as not accessed for longer time.

The list shows not seemingly hot regions, and only minimum access pattern
