Make more time related validation related error messages more user-fr…

…iendly

Although the datetimes that appears in error messages are UTC, the generated error messages do not reflect that (eg. IDX10223: Lifetime validation failed. The token is expired. ValidTo: '1/31/2023 2:45:58 PM', Current time: '2/3/2023 1:16:14 PM').

Adding the '(UTC)' additional context makes this clearer.
