Add Gitea workflow for testing and E2E integration

- Created a new workflow file (.gitea/workflows/test.yml) to automate testing processes.
- Defined jobs for basic testing and end-to-end (E2E) testing using Jest, Supertest, and Playwright/Cypress.
- Included steps for dependency installation, plugin building, and Strapi server management during E2E tests.
