Fixes https://github.com/twentyhq/twenty/issues/11566 + translates dates
- Date display bug: We had an issue with date (not date time) display
depending on the timezone the user had selected. The date is stored in
the db as yyyy-mm-dd, eg. 2025-05-01 for **May 1st, 2025**. When
returned this date is formatted in a UTC DateTime at midnight, so
2025-05-1 00:00:00. Then when displaying the date we were converting
this date using the timeZone, so 2025-04-30 17:00:00, thus displaying
**April 30th, 2025**. The fix chosen is that we should not take into
account the timezone for date (not date time!) displays as we always
want to show the same date.
- Date translation: dates were not translated, not in their default
display (_May 1st, 2025_) nor in their relative display (_about a month
ago_). The lib we use for date formatting, date-fns, offers a
translation option with pre-built `Locale`s from their lib.
Unfortunately and surprisingly we cannot just use directly string locale
codes (like `fr-FR`), cf [open issue on
date-fns](https://github.com/date-fns/date-fns/issues/3660). A util was
introduced to offset this by dynamically importing the right date-fns
Locale based on the locale code.
