Remove ci-test-full recipe and simplify comments

This removes the `ci-test-full` justfile target (see GitoxideLabs#1674), and
simplifies and shortens some comments in the justfile, since the
distinction between `ci-test` and `ci-test-full` no longer has to
be explained, and since some other parts of the comments are no
longer applicable (GitoxideLabs#1673).
