License attribution not displayed on Github

[miloserdow]

I noticed that the license attribution for nearcore repository is not being displayed on its Github page.

This might be caused by #4798.

Screenshot of the issue

Expected behaviour (taken rust-lang as an example)

Version (please complete the following information):

• nearcore master

[nagisa]

#4798. So this not accidentally showing seems actually intended as not all of nearcore is licensed under these licenses, apparently.
