[PR #11464/8b0ce3e2 backport][stable-12] community.general.copr: clarify includepkgs/excludepkgs (#11476)
community.general.copr: clarify includepkgs/excludepkgs (#11464)

At first glance, includepkgs seems to be something that would install
the package name from the given copr repo.  This isn't helped by the
example that says "Install caddy" which very much looks like it is
installing the package from the repo.  Not only did I, a human,
hallucinate this behaviour, so did a large search engine's AI
responses to related queries.

In fact these are labels to vary what packages DNF sees.  Clarify this
by using wording and examples closer to the upstream documentation [1]

(cherry picked from commit 8b0ce3e28f)
