Fix ssl enabled property in Redis config for Spring Boot 3.1 (#254)

* Fix ssl enabled property

In Srping Boot 3.1, the flag is ssl.enbled not ssl, as in the java doc here: https://docs.spring.io/spring-boot/docs/3.1.8/api/org/springframework/boot/autoconfigure/data/redis/RedisProperties.Ssl.html#isEnabled()

* Using Boolean instead of String

* Redis SSL properties change: Add test
