Format date properties

[schiwekM]

Hi colleagues,

currently if a cds.Date property is modified it is shown as '2022-12-01' in the change log. This is not really user friendly and thus this PR adds date formatting so the dates show up as they would in UI5, e.g. '01 Dec 2022'

BR,
Marten

@Sv7enNowitzki could this one be considered too? Would be great to have it for improved UX, because business users at not to used to the ISO format for dates.

Hello Marten, I have to reject this PR.
Change log Dates are indeed meant to be technical, and require to be e.g. sortable and searchable.
The use cases we encounter frequently are, that the change logs aren't even shown with the built-in UI facet, but rather in a separate, dedicated change-log UI. Since the format is statically determined at write-time, and not dynamically when reading, localizing what was written is not a good idea, especially when searching for a specific date in the logs by users in different locales.

Hi Nik, I just checked again and the logic is only run in an after READ handler on ChangeView so on DB it is as intended still in ISO format.
