…ependency Move `istanbul-lib-instrument` from dependencies to optional peer dependencies. This helps reduce the transitive dependency count for new projects. BREAKING CHANGE: `istanbul-lib-instrument` is now an optional peer dependency. Projects using karma with code coverage enabled will need to ensure that istanbul-lib-instrument is installed. Note: `ng update` will automatically add this dependency during the update process.
Add a new schematic migration to automatically add istanbul-lib-instrument to devDependencies for projects that use Karma. Covered builders: - @angular-devkit/build-angular:karma - @angular/build:karma - @angular/build:unit-test (when runner is 'karma')
