fix(gradle): make ci inputs same as test inputs (#31198)

<!-- Please make sure you have read the submission guidelines before

-->

<!-- Please make sure that your commit message follows our format -->
<!-- Example: `fix(nx): must begin with lowercase` -->

<!-- If this is a particularly complex change or feature addition, you
can request a dedicated Nx release for this pull request branch. Mention
someone from the Nx team or the `@nrwl/nx-pipelines-reviewers` and they
will confirm if the PR warrants its own release for testing purposes,
and generate it for you if appropriate. -->

## Current Behavior
<!-- This is the behavior we have today -->

current ci test target does not contain inputs of test, it just contains
the test source file

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->
change the ci targets to contain inputs of test
