Fixup typography changes release notes between 1.23 and 1.14

Hotfix I595feec9a to REL1_23 changes release notes directly
in REL1_23 without applying to master first. The files are now
out of sync.

* Sync the line in RELEASE-NOTES-1.23 with what is in REL1_23
  (basically cherry-picking hotfix I595feec9a from REL1_23 to
  master here).

* Move the remainder to RELEASE-NOTES-1.24.
