feat: Add support for Vavr's Try monad to trigger transaction rollbacks

Updated the Spring Framework documentation to include an example of using Vavr's Try monad to trigger transaction rollbacks when a @Transactional-annotated method returns a Failure. The modified documentation demonstrates how to use Try in a transactional method and how to check if an exception has been wrapped inside a Try.Failure instance. Additionally, a link to the official Vavr documentation was added to provide more information on the Try method.

+However, starting with Spring Framework 5.2.0 the default configuration also provides support for Vavr's `Try` method to trigger transaction rollbacks when it returns a 'Failure'. This allows you to handle functional-style errors using Try and have the transaction automatically rolled back in case of a failure.
