Schedule: Allow custom localization

Description In PF < 7.0 the Schedule component was configured using PF locales: https://github.com/primefaces/primefaces/wiki/Locales

When we upgraded to Full Calendar 4.X for PF 8.0 it was decided to use the already built translations that come with FullCalendar so if you used locale="fr" for French you would get the French translation from FullCalendar: https://github.com/fullcalendar/fullcalendar/blob/master/packages/core/src/locales/fr.ts

Full list of locales: https://github.com/fullcalendar/fullcalendar/tree/master/packages/core/src/locales

However the ability to override the default or customize the localization was lost.

Hi all,

I made the following changes;

• Added slotLabelFormat to primefaces-p.taglib.xml https://fullcalendar.io/docs/slotLabelFormat
• Removed monthNames, monthNamesShort, dayNames and dayNamesShort; https://fullcalendar.io/docs/v4/upgrading-from-v3 Users can use the extender method to customize these options. Please see “Locales” section in the above link.
• For backward compatibility, options supported by FullCalendar (not related to any plugin) have been merged with PrimeFaces locale.
• Now two separate local values ​​are passed to the widget for FullCalendar and PrimeFaces.locales. Please see this case; PrimeFaces.locales -> pt_BR FullCalendar -> pt-br Maybe there will be two separate locale attributes for Schedule component in the future.

@melloware It seems the removed localizations options pertain to date and time formatting. By default, FullCalendar uses the native built-in Intl.DateTimeFormat for localizing dates and times. Additionally, there’s also the moment plugin (which we use). The built-in formatter is used when the date/time format is an object, moment is used when the date/time format is a string (e.g. “dd-MMMM”).

It’s possible to customize the dates and times shown in the FullCalendar by setting a date/time format (e.g.titleFormat), and update moment’s localization options, like this:
