This commit extends the 2018 Contributor Stories repository by moving us
to GitLab, with a similar introduction and issue template. We will begin
to promote these Contributor Stories as a way for people to share their
appreciation and gratitude as Fedora Appreciation Week draws near in
November 2023.
