Add 'Run App' step to the GitHub workflow

This commit introduces a new step in the GitHub actions workflow file. 'Run App' step, which runs the development server, has been included right before running the Playwright tests. This change is essential for seeing a real-time reflection of changes in the dev server during the testing phase.
