…igurations Introduces a new migration that removes `karma.conf.js` files from projects if they contain only the default generated configuration. When a file is removed, the corresponding `karmaConfig` option in `angular.json` is also removed from the project's test target. The Angular CLI now provides a default Karma configuration internally, making explicit configuration files unnecessary for projects that do not require customization. This migration helps to clean up and simplify existing projects by removing these now redundant files. The migration will safely skip any `karma.conf.js` file that has been modified or contains values that cannot be reliably analyzed.
