Add Environment Setup Step in CI Workflows

- Introduced a new step in both `pr-test.yml` and `unit-test.yml` workflows to set up environment variables for database configuration.
- Enhanced the environment setup to conditionally configure database connection strings based on the selected database driver, improving test reliability and flexibility.
- Created necessary directories for SQLite database storage when not using MySQL, ensuring proper environment preparation for tests.
