[localization: legacyDateCalendarCustomizing] Islamic calendar date mapping no longer works

[amdev138]

Bug Description

Hi team,

OpenUI5 has changed the dateMapping getter's name from getLegacyDateCalendarCustomizing to getCustomIslamicCalendarData via, openui5/commit/ac04fe2e2502. So when the formatter tries to find the mapping via ,Islamic.js#L215, the mapping is undefined since the FormatSettings.ts#L28 only has the old getter.

Note: Issue exists in main, however, current ui5-wc version we are using in production is 1.24.7 and the issue exists here too (which are the versioned links listed above)

Thanks,
Allen

Affected Component

Date Picker/Calendar Components/DateFormat

Expected Behaviour

The Islamic date mapping in the configuration should be honored.

Isolated Example

https://stackblitz.com/edit/js-hwh96q?file=index.html

Steps to Reproduce

1. The ask is pretty straight forward here and I would bet a unit test would detect this. But you can also go to stackblitz which has the init script with the mapping included.
2. Open the date picker.
3. See Rabi 1446. Thursday the 8th.
4. 
5. The expectation is it would be Thursday the 9th.
6. 
7. You can set a breakpoint on line 215 in Islamic.js and see that the date mapping is undefined.
