Fix indentation style of formatter

[lw64]

Currently:

var animation_timed = new Adw.TimedAnimation (
                                              progress_bar, // Widget
                                              0, 1, // Initial value, final value
                                              1500, // Duration (in milliseconds)
                                              target_timed // Animation target
    ) {
    easing = EASE_IN_OUT_CUBIC
};

But it should rather be:

var animation_timed = new Adw.TimedAnimation (
    progress_bar, // Widget
    0, 1, // Initial value, final value
    1500, // Duration (in milliseconds)
    target_timed // Animation target
) {
    easing = EASE_IN_OUT_CUBIC
};
