Fix incorrect model license

Hi

@nielsr


@merve
, thanks for adding a model card!

However, the license you used was wrong. The license for the code is Apache 2.0, but the license for the release weights are CC BY-NC 4.0 (unfortunately, this is just a requirement from using ImageNet data).

I'll open this PR on the other models as well.
