fix: Add retry logic to git operations in deploy-application-code.yml

- Add retry logic (5 retries, 10s delay) to git clone and update tasks
- Handle 504 Gateway Timeout errors from Gitea gracefully
- Fail with clear error message if all retries are exhausted
- Prevents workflow failures due to temporary Gitea unavailability
