Added override to enable using Jasmine 5.

Since Karma is deprecated, there's not going to be an update for karma-jasmine. An override is the only way to upgrade until the migration to the Jasmine web runner (which - according to the deprecation annoncement - possibly requires an Angular update).
Workaround from karma-runner/karma-jasmine#333.
