Update .gitignore, remove obsolete Woodpecker build file, and add e2e-runner service to docker-compose

- Added 'e2e/results/' to .gitignore to exclude end-to-end test results.
- Deleted the outdated Woodpecker build-arm.yml file as it is no longer needed.
- Introduced a new e2e-runner service in docker-compose.test.yml to facilitate end-to-end testing with dependencies on other services.
