[activity-feed] Fix date formatting literal for Safari simplify date return (#4783)

## Description

This pull request simplifies the date formatting logic in the
`ActivityFeedStepComponent` by removing custom string manipulation and
returning the formatted date directly.

- Simplified date formatting in `ActivityFeedStepComponent` by returning
the result of `#intlDateTimeFormat.format(date)` directly, instead of
splitting and reconstructing the formatted string.
