Instead of having json errors in transcript acquisition and conversion cause errors, have transcription conversion and acquisition simply return an error message in the transcription which can prompt a change from the user. Although not uploading a transcript is handled, transcripts can often cause errors in edit, export, and other activities due to json errors. These errors block the entire use of these features, so to allow for reupload, etc, we add an error message instead of transcript and log the event. In response to [TNL-8539](https://openedx.atlassian.net/secure/RapidBoard.jspa?rapidView=580&projectKey=TNL&modal=detail&selectedIssue=TNL-8539) Testing: Unit tests coverage is included in the PR. Upload, import, and export of courses with transcriptions is also easily hand-testable. Just create a video in studio, add an irrelevant transcript. Then try to import, export, and edit the problem. Expected behavior is success.
