LOG: [NFC] update comments from an earlier version of SuffixTree (#89800)

LeafChildren is used in an earlier version of the SuffixTree
implementation to keep track of each nodes' leaf nodes. In the
new/current version, this variable is no longer used, but a comment is
left behind. This patch updates the comment.
