Update CI script to properly fail if `projectHealth` gradle task has dependencies to fix

https://github.com/assertj/assertj-generator-gradle-plugin/pull/66 shows a failing `projectHealth`, however it passes the CI action:

Example that has this support:
https://github.com/Nava2/kaff4/blob/c689f6f8d9e2552a1dc3dddaf051e1a0e2256742/.github/workflows/gradle-check-pristine.yml#L25

It _might_ be easier to add support to the [gradle plugin](https://github.com/autonomousapps/dependency-analysis-android-gradle-plugin) to support failing instead of passing.

Inspect the repository's GitHub Actions workflow and the projectHealth Gradle task invocation, then compare its behavior with the linked gradle-check-pristine.yml example. Confirm how dependency failures are reported and consider the linked dependency-analysis Gradle plugin before defining completion as CI failing when projectHealth has fixable dependencies.
