Docs/ABI/damon: document tried_regions probe hits

Browse Source 
The 'tried_regions/<R>/probes/<P>/hits' file, added in commit 5b0de1bc33
("mm/damon/sysfs-schemes: implement probe/hits file"), is described in
usage.rst but missing from the canonical ABI document.

Document the 'probes/' directory and the 'probes/<P>/hits' file.
