Replace GitLab integration with Gitea in issue reporting

Migrated issue reporting functionality from GitLab to Gitea. Updated environment variables, dependencies, and configuration references to support Gitea. Introduced `GiteaClient` for communication with the Gitea API and refactored related code and tests to align with the new integration.
