Update Gradle wrapper and enhance logging in DotEnvConfiguration

- Updated Gradle wrapper distribution URL to version 9.0.0.
- Replaced System.out logging with SLF4J logging in DotEnvConfiguration for better logging practices.
- Added @JsonIgnoreProperties annotation to RestResponseSlice to ignore unknown properties during JSON deserialization.

These changes improve project configuration and logging consistency.
