IDE-325 Integrate SonarQube Analysis with Multi-Job Coverage

[harshsomankar123-tech]

Reference:
Jira Ticket: (https://catrobat.atlassian.net/browse/IDE-325)

Follow Up of : #5183

Description
This PR integrates SonarQube Cloud analysis into the Catroid CI workflow. It adds a dedicated analysis job that aggregates coverage data from both unit tests and instrumented tests (emulated tests).

Previously, SonarQube analysis was restricted for fork PRs due to secret access limitations. By moving this branch to the main repository, we can now verify the SonarCloud token setup and enable full code quality visibility.

Changes:

• Configured the workflow to trigger SonarQube analysis upon pushes and pull requests to the develop branch.
• Integrated Jacoco/Sonar plugins to track and upload coverage data.
• Ensured the job properly identifies the project key and organization within the SonarQube environment.
