[chethann007]

This PR adds a GitHub Actions workflow for PR code coverage and quality checks to the search-indexer flink job of Sunbird-Knowlg repository.

PR Code Coverage

• Triggers: When a pull request is created against any branch.
• Functionality:
  • Builds the project
  • Runs unit tests
  • Generates a coverage report using JaCoCo
  • Performs static code analysis with SonarQube

This workflow ensures that every proposed change is validated for code quality and coverage before merging.

Pull Request Overview

This PR introduces a GitHub Actions workflow to automatically build, test, generate coverage reports, and run SonarQube analysis on the search-indexer module whenever a PR is opened. It also updates the test configuration to load schema settings from an environment variable.

• Replace hard-coded schema settings in test.conf with an environment-driven block.
• Add a new coverage-search-indexer job in .github/workflows/pr-actions.yml to run Maven tests, generate JaCoCo reports, and execute SonarQube analysis.

• [nitpick] Consider documenting the expected format or providing a default value for 'SCHEMA_BASE_PATH' to avoid runtime misconfiguration when the environment variable is unset.

  basePath = ${?SCHEMA_BASE_PATH}

.github/workflows/pr-actions.yml:281

• Include 'SCHEMA_BASE_PATH' in the environment and pass it as a Maven property (e.g., -DSCHEMA_BASE_PATH=$SCHEMA_BASE_PATH) during the SonarQube analysis step to ensure consistency with the test configuration.

• [nitpick] Align the indentation of the newly added 'schema' block with the surrounding configuration entries (e.g., two spaces) for consistency and readability.
