Schedule: Locales not fully respected

All European locales have first day of the week Monday [link]. But e.g. Norwegian is stariting by Sunday (søn.) in p:schedule component, which is wrong.

All, except EN schould be Mon:

PF version	EN	DE	SV	NO
8.0	Sun	Mon	Mon	Sun
8.0.2	Sun	Mon	Mon	Sun
8.0.5	Sun	Mon	Mon	Sun
snapshot*	Sun	Sun	Sun	Sun

• FullCalendar demo is working correctly: https://fullcalendar.io/docs/locale-demo. E.g if I choose “nb” locale (nb - Norwegian Bokmål, nn - Norwegian Nynorsk), then week starts by monday (man.).

• Setting of p:schedule weekNumberCalculation to “ISO” does not help, even if FullCalendar is saying “If weekNumberCalculation is set to ‘ISO’, this option defaults to 1 (Monday)”. https://fullcalendar.io/docs/firstDay

I added an Integration Test to our suite so this is caught in the future.

    @Test
    @Order(4)
    @DisplayName("Schedule: GitHub #6496 locale switching")
    public void testLocales(Page page) {
        // Arrange
        assertButton(page, "fc-today-button", "Current Date");
        assertButton(page, "fc-dayGridMonth-button", "Month");
        assertButton(page, "fc-timeGridWeek-button", "Week");
        assertButton(page, "fc-timeGridDay-button", "Day");

        // Act
        page.buttonFrench.click();

        // Assert
        assertButton(page, "fc-today-button", "Aujourd'hui");
        assertButton(page, "fc-dayGridMonth-button", "Mois");
        assertButton(page, "fc-timeGridWeek-button", "Semaine");
        assertButton(page, "fc-timeGridDay-button", "Jour");
        assertConfiguration(page.schedule.getWidgetConfiguration());
    }

OK I found the problem and fixed it. the locales need to be added now for FullCalendar to be aware of them
