refactor(@angular-devkit/build-angular): remove redundant spinner coloring

This commit refactors the usage of the `Spinner` class in `@angular-devkit/build-angular` builders by removing explicit `colors.redBright` calls when invoking `spinner.fail()`.

The `Spinner.fail()` method already applies red bright coloring internally. This change centralizes the styling logic within the `Spinner` class and prevents redundant coloring or unnecessary dependency usage at the call site.
