license metadata populated incorrectly

[bendichter]

Describe the issue

When you create a new dandiset, the license metadata is created incorrectly

It should be sent as a list with one element, but it is sent as a string, so the API instead breaks up the string and has a license for each letter.

Steps to Reproduce

Just go through the GUIDE tutorial and create a new dandiset on staging

Operating System

@rly do you think you could look into this?

Does it make sense to have a dandiset with both CC-BY-4.0 and CC0-1.0? DANDI allows both

see https://gui-staging.dandiarchive.org/dandiset/213889/draft

We could allow both, but if that's a bug or it is not a recommended practice to have both, we could require the user to select only one.

Looking at the DANDI page, it seems like it may be intentionally allowing multiple licenses. I'd ping DANDI for clarification.

For NWB GUIDE purposes, I think limiting the license selection to one makes sense. (Otherwise, I would make the license selector a multi-select.)

See #904 for the change that broke this.

It's fine to only allow one, but I think it needs to be passed as a list of length 1
