deps: avoid updates of indirect (transitive) deps

Problem:
Dependabot is updating transitive deps (`package-lock.json`) instead of
only dependencies that we explicitly declare (`package.json`).

Examples:
#670
#669

Solution:
Revert `dependency-name: '*'`, which was only an experiment.
The remove of `dependency-type: 'development'` in 15dfb02 should be
enough to fix the problem of missing Dependabot updates, without also
inviting updates of transitive deps.
