NcML previewer not working

[pdurbin]

In a comment from 2023 there's a screenshot showing that the file at https://dataverse.harvard.edu/file.xhtml?fileId=6938801&datasetVersionId=340765 was being displayed properly in the NcML previewer we added a while back (see #9242). Here's how it looked back then:

Unfortunately, it's not working anymore. Now it looks like this:

Weird - it looks like the scripts in that dir at gdcc have not changed in two years (which makes sense as we only do updates in the betatest subdir and new releases.)

Ah - I bet it got changed to use signedURLs via a config change at Harvard and this line isn't quite signedURL ready: https://github.com/gdcc/dataverse-previewers/blob/4711800f67de961ca5326e88b3e0c710a7d1301a/previewers/v1.4/js/ncml.js#L12

Workaround is to change the config for it back to using api key.

My guess is that adding a line like this would fix it: https://github.com/gdcc/dataverse-previewers/blob/4711800f67de961ca5326e88b3e0c710a7d1301a/previewers/betatest/js/video.js#L13C1-L13C82

Any fix should go in the betatest dir though and the config would then need to be updated to get the new version.

In any case, probably not a dataverse repo issue/no changes needed in Dataverse/not a change in Dataverse that caused it.
