refactor: Remove wal-g v3 and simplify build

- Removes the `wal-g-3` Nix package definition and all associated build/installation steps from Dockerfiles and Ansible playbooks.
- Standardizes on `wal-g-2` as the sole WAL-G version used, simplifying the build process and reducing complexity.
- Cleans up related checks and package definitions in Nix.
