joi: Quadratic regular-expression backtracking in `Joi.string().isoDate()`

Impact Any application that validates a user-supplied string with Joi.string.isoDate can be stalled by a single request. One of the regular expressions the rule runs over the input was unanchored, so a valid ISO date followed by a long run of fractional-second digits made the regex engine restart...
