Data migration updates

[rtibbles]

Summary

Description of the change(s) you made

• Fixes a remaining bug with the set file duration job whereby even with a fully streamed file, the duration cannot be inferred
• Adds a management command and make file entry to infer whether video resource nodes should have the has captions metadata applied to them, and applies it

Manual verification steps performed

1. Ran the new management command, confirmed that it added the label for a node with subtitles that matched the language of the video.
2. Ran it again and confirmed no additional nodes were updated
