Document ability to replace UI component by using ComponentRegistration with replaceComponent()

[alexbudarov]

We can replace standard UI components with apparently public Jmix API:
Example:

    @Bean
    public ComponentRegistration datePicker() {
        return ComponentRegistrationBuilder.create(ExtendedDatePicker.class)
                .withComponentLoader("datePicker", DatePickerLoader.class)
                .replaceComponent(TypedDatePicker.class)
                .build();
    }

public class ExtendedDatePicker<V extends Comparable> extends TypedDatePicker<V> {

    public static final String FAST_INPUT_DATE_FORMAT = "ddMMyyyy";

    @Override
    protected void initComponent() {
        super.initComponent();
        getI18n().setDateFormats(
                messages.getMessage("dateFormat"),
                FAST_INPUT_DATE_FORMAT
        );
    }
}

But Jmix docs don't contain such information.
AI assistant also doesn't have any idea about such ability:
