[PATCH 6.18.y] Docs/ABI/damon: fix typo in intervals_goal sysfs path

[SJ Park]

From: Song Hu <husong@kylinos.cn>

Patch series "Docs/ABI/damon: sysfs ABI document fixes and additions", v2.

This series fixes typos and fills in missing entries in the DAMON sysfs
ABI document (Documentation/ABI/testing/sysfs-kernel-mm-damon).

Patch 1 fixes a path typo, "intrvals_goal" -> "intervals_goal", in four
What: entries; the documented path points to a non-existent directory, so
it is Cc'ed to stable.

Patch 2 fixes two further typos ("WDate:", "manimum").

Patches 3 and 4 add ABI entries that exist in the kernel and are already
described in usage.rst but are missing from the canonical ABI document:
the 'update_tuned_intervals' state command (patch 3) and the
'tried_regions/<R>/probes/<P>/hits' file (patch 4).

This patch (of 4):

The ABI document spells the DAMON sysfs directory as "intrvals_goal"
(missing 'e') in four What: entries, but the kernel creates it as
"intervals_goal" (mm/damon/sysfs.c).  Following the documented path
therefore yields a non-existent directory.
