docs(changes): drop catalog titles from the pending TMDB spelling note

Release notes are published verbatim — into CHANGELOG.md, the GitHub release

folding bug with three series names taken straight from a user's own portal
catalog, which is not ours to publish. Name the letter instead of the titles:
the example is clearer for a reader who does not know those shows anyway.
