v0.129.0

Adds functionality to redirect to an app "page" containing instructions (and eventually a link to KB article) for how to update the uploader when jellyfish responds to a POST of upload metadata with an error stating that the version of the uploader is out of date and no longer supported.

We have not yet configured jellyfish to respond with this error given any previously published version of the uploader - so this change is a no-op to users until we update jellyfish to require a higher version of the uploader.
