Update CI versions

silex/emacs no longer provides old minor versions, so test_in_docker.sh
and lint_in_docker.sh now test for only the latest minor version of each
major versions.

Silex/docker-emacs#62 (comment)

.github/workflows/run-test.yml, which uses nix-emacs-ci via
purcell/setup-emacs, still tests against older minor versions.
