Describe the bug

Dates on event cards are not being formatted using intl locale.

To reproduce

1. Go to https://ethereum.org/zh/community/events/
2. Notice date format in event cards compared to date at the top of the page.

Expected behavior

Despite the contents of these cards not being translated into other languages, I would expect these dates to be rendered according to the locale.

The Intl.DateTimeFormat should be used by passing the current locale and the date to render accordingly.
