Change English (EU) language setting to show dates in the DD-MM-YYYY format

[Octa_Bahjan]

There does exist an international standard (ISO 8601) for writing dates, which avoids most of the confusing cases. It should be used for dates everywhere unless there happens to be a good reason for some other format.
YYYY-MM-DD. So July 8, 2023 would be written as 2023-07-08.

+1 on ISO 8601, but customisability would be the best IMO so that the player can choose the option that makes the most sense to them
