docs(releases): the 18.1 page's commit-hash caution now describes only the published tarballs

#25804 rewrote the repository's 18.1.0 CHANGELOGs so each entry names its
own commit; the published tarballs still read 3937697 and are never
republished.

Fixes #25806

 Read the 18.1.0 CHANGELOGs with two cautions:
 
-- **The commit beside an entry is mostly not its own.** 260 of the 265 entries
-  open with `3937697`, the commit of #25605 that reverted the first cut and
-  re-added every pending changeset; only the five changesets merged after it
-  carry their own commit. The same is true in the published tarballs: all 34
-  entries of `@objectstack/cli@18.1.0`'s `## 18.1.0` section read `3937697`.
-  To find the change behind an entry, search its headline in the repository's
-  history; this page cites each entry's own commit.
