ci: Fixes for failing workflows

- Updated the `gl-testing` Dockerfile to use Poetry `1.8.2`, as Poetry
`v2.x.x` installs the latest version of `pyln-grpc-proto` (`24.2.1`),
which causes the `mypy glclient` check to fail. Poetry `1.8.2` installs
`pyln-grpc-proto` version `0.1.3`, which works seamlessly with the CI.

- Added a check to ensure the group exists before adding it in the Docker.

- clnVersionManager: Locked Poetry version to `1.8.2` to allow for a
coordinated upgrade in the future.
