chore(qa): drop obsolete stale-prose NOTE from records-forms.action-location-matrix (#7633)

PR #7540 rewrote RecalcSelectionAction's TSDoc in
examples/app-showcase/src/ui/actions/index.ts, so the NOTE clause
planted by #7323 (flagging that TSDoc as narrating the stale
pre-objectui#3142 rule) is now false. Delete the NOTE clause from the
second source entry of records-forms.action-location-matrix, keeping
the source citation itself intact.

Fixes #7547
