[CI] Update CI to run on Haloween 2024

The maintenance was focused on making it passing. The following things were
updated/improved:
- Remove Emacs-27: no longer supported by purcell/setup-emacs GitHub action
¯\_(ツ)_/¯.
- Install nix sqlite3^dev for emacs-28. The `sqlite3` package is still having
issues loading, but suppressing error there when running in CI.
- Bump checkout action to v4.
- Lengthten printed messages in CI, the more logs the better
- Updated build matrix.
