connorhaugh 0d26738fce fix: Prevent Transcripts from Failing Export, Edit (#28242)
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.

Status: Deprecated (DEPR-24)

Responsibilities
================
XModules render specific course run content types to users for both authoring and learning. For instance, there is an XModule for Videos, another for HTML snippets, and another for Sequences. This package provides both the implementations of these XModules as well as some supporting utilities.

Direction: Convert and Extract
==============================
XModule exists today as a complex set of compatibility shims on top of XBlock (all XModules currently inherit from XBlock). The goal is for all XModules to either be converted into pure XBlocks or be deleted altogether. Extracting them into separate repositories would be ideal, but even just converting them to pure XBlocks would significantly simplify the runtime.
