Spring Add Spring Boot Converter to "Configuring a Global Date and Time Format" documentation

Update the "Configuring a Global Date and Time Format" so that its application does not break support of Duration properties readable format (1s, 2h,3d...)

Without ApplicationConversionService.addApplicationConverters(conversionService) loading Duration annotated with @Value would fail because the DurationConverter registered within the DateTimeFormatterRegistrar does not support "readable" Duration format.

@m-dutaut ApplicationConversionService is a Spring Boot concept, and so is the feature you are referring to. We can't document that here.
