Update temporal accessor to use specific cftime objects

- Update format of `decode_non_cf_time()` conditional statement
- Update `time_cf` with encoding dict attributes (xarray behavior)
- Update `test_dataset.py` and `test_temporal.py` with specific `cftime` date_type objects
- Add `xesmf` to `dev.yml`
- Remove `Jupyter` setting from VS Code workspace
