chore(license-report): add `projects = [project]` to licenseReport to avoid deprecation warnings (#3933)

# Description of Changes

- **What was changed**  
Added the line `projects = [project]` to the `licenseReport`
configuration in `build.gradle`.

- **Why the change was made**  
Without specifying `projects`, the `licenseReport` plugin attempts to
resolve configurations from a non-project context, resulting in numerous
deprecation warnings. Explicitly setting `projects = [project]` scopes
the report to the current project and silences these warnings.
