01b1348d - stdlib/Dates: Fix doctest regex to handle DateTime with 0 microseconds (#58981)

stdlib/Dates: Fix doctest regex to handle DateTime with 0 microseconds (#58981) The `now(UTC)` doctest can fail when the DateTime has exactly 0 milliseconds, as the output format omits the fractional seconds entirely (e.g., "2023-01-04T10:52:24" instead of "2023-01-04T10:52:24.000"). Update the regex filter to make the milliseconds portion optional by using `(\\.\\d{3})?` instead of `\\.\\d{3}`.
