[BUGFIX] Fix the CI build with the lowest dependencies (#170)

- fix a syntax error in the `ci.yml`
- also update/downgrade transitive dependencies
- add a conflict with broken versions of typo3/class-alias-loader
- use a Composer-2-compatible version of `helhum/typo3-composer-setup`
- start running the unit and functional tests with the lowest
  dependencies on GitHub Actions

Fixes #50
