Use spring-cloud-function-dependencies in time-spel-log

This replaces the use of `spring-cloud-dependencies` in time-spel-log
with `spring-cloud-function-dependencies` in order to:

- narrow dependencies to only what the sample needs

- pick up spring-cloud/spring-cloud-function#1224 which will be
  released earlier than Spring Cloud `2024.0.1` in Spring Cloud Function
  `4.2.1`
