`eopf-geozarr validate` returns 0 compliant and 0 non compliant variables

I receive the output below when running the eopf-geozarr validate command on an optimized geozarr generated by convert_s2_optimized :

✅ Dataset appears to be GeoZarr compliant

Although the Dataset appears compliant, the number of variables checked is 0. I ran it also on the (v0) optimized geozarr and encountered the same behavior.

To reproduce the result and create locally a similar geozarr, you can run the example notebook https://github.com/lhoupert/eopf-explorer-notebook/blob/main/notebooks/00_download_and_convert_eopf_to_geozarr.ipynb .

Then go to the downloaded data folder data/geozarr and run eopf-geozarr validate S2C_MSIL2A_20250712T112141_N0511_R037_T30UWF_20250712T145316_geozarr_v1.zarr

Relates to #86 if we want to use the validate command to check the compliance.

Align validate command with pydantic zarr
