Fix missing dependency in DFP Grafana example (nv-morpheus#1977)

- Dependencies for DFP container were recently moved from `examples/digital_fingerprinting/production/conda_env.yaml`  to `conda/environments/examples_cuda-125_arch-x86_64.yaml` but `python-logging-loki` was not included.
- Add `python-logging-loki` to `example-dfp-prod` in `dependencies.yaml`.
- Remove `conda_env.yaml` since it's no longer being used anywhere.
