## Description
<!-- Provide a detailed description of the changes -->

Gradle wrapper no longer accepts arguments, resulting in failure seen
[here](https://github.com/openfga/spring-boot-starter/actions/runs/12638979598/job/35216388903).
This change removes the argument in favor of running directly, as
documented
[here](https://github.com/gradle/actions/blob/main/docs/deprecation-upgrade-guide.md#using-the-action-to-execute-gradle-via-the-arguments-parameter-is-deprecated).
