Tools for bulk changes to help text and settings

[joemull]

Problem

We have an upcoming set of edits to model help text and Janeway setting descriptions that will result in very large migrations, if we just auto-generate them. Or we could stitch the help text changes into existing migrations manually, as we usually do for small changes, but that would be very time-intensive. It will also be time-intensive to produce the setting update migration by hand.

Proposed solutions

• Ignore help text and verbose names in migrations, using the approach described by Cynthia Kiser.
• Write a management command that can generate appropriate JSON to paste into a data migration to feed to utils.migration_utils.update_default_setting_values, based on a git diff of journal_default.json.
• We then need to actually write the setting migrations for Updating in app documentation #4916.

It probably makes sense to do this work on the same branch as the recent help text and description edits, #4916.
