Docs/mm/damon/design: fix two typos

Patch series "Docs/damon: minor fixups and improvements".

Fixup typos, clarify regions merging operation design with recent change,
add access pattern snapshot example use case, and improve readability of
the design document and subsystem documents index by
reorganizing/wordsmithing and adding links to other sections and/or
documents for easy browsing.

This patch (of 9):

Fix two typos.  The first one is just a simple typo: s/accurach/accuracy/

The second one is made by the author being out of their mind.  'Region
Based Sampling' section of the doc is mistakenly calling the access
frequency counter of region as 'nr_regions'.  Fix it with the correct
name, 'nr_accesses'.
