#159 LICENSE: Add Fedora default content license
Merged by mattdm. Opened by jflory7.
Fedora-Council/ jflory7/council-docs add/license  into  main

This commit adds the Creative Commons Attribution-ShareAlike 4.0
International license to the repository as the default license for all
content stored here. Technically, this is implied already because of
Fedora's existing legal policies and documentation, but this makes an
implicit assumption into an explicit definition. It also ensures the
license is copied between git repo clones and forks.

The legal text was pulled directly from Creative Commons:
