Clarify license

[xsuchy]

As part of https://fedoraproject.org/wiki/Changes/SPDX_Licenses_Phase_1 I wanted to check what SPDX string will be for this package. Currently, the spec file uses: CC-BY-SA. Which is ambiguous:

 $ license-fedora2spdx 'CC-BY-SA'
Warning: more options on how to interpret CC-BY-SA. Possible options: ['CC-BY-SA-4.0', 'CC-BY-SA-3.0', 'CC-BY-SA-3.0-DE', 'CC-BY-SA-3.0-AT', 'CC-BY-SA-2.5', 'CC-BY-SA-2.1-JP', 'CC-BY-SA-2.0', 'CC-BY-SA-2.0-UK', 'CC-BY-SA-1.0']
{{pick CC-BY-SA choice}}

Looking at this project and the code - it seems that the correct one will be 'CC-BY-SA-4.0'. But I am puzzled by the presence of:

• CC-BY-4.0
• CC0-1.0
• Free-Art-1.3

Is anything licensed under this license? If not, should these files be present here? If yes, should the license be changed?

* [CC-BY-4.0](https://github.com/fedoradesign/backgrounds/blob/main/CC-BY-4.0)

* [CC0-1.0](https://github.com/fedoradesign/backgrounds/blob/main/CC0-1.0)

* [Free-Art-1.3](https://github.com/fedoradesign/backgrounds/blob/main/Free-Art-1.3)

Those licenses were for the supplemental wallpapers in extra sub-packages. They can be ignored as I will remove them from the branch to avoid confusion.

Closing as resolved.
