Fix NWCSAF reading for NOAA-21

[ninahakansson]

Reading NWCSAF products for NOAA-21 failed. I got the error message:
ValueError: Could not find dataset named cmic_reff_pal in ancillary variables for dataset 'cloud_drop_effective_radius' but I think it was unrelated to reading NOAA-21 data. I updated the dictionary with VIIRS and METimage satellites.

Why not add support for JPSS-3/NOAA-22 as well now that you are add it?
We know that the name will be NOAA-22 if JPSS-3 launch is successful. It is supposed to be launched in 2027, but I guess it is likely it will be delayed or postponed a bit, but anyway it is still quite "soon".

RTD is failing because of:

/home/docs/checkouts/readthedocs.org/user_builds/satpy/conda/2481/lib/python3.10/site-packages/satpy/enhancements/__init__.py:docstring of satpy.enhancements._jma_true_color_reproduction:6: ERROR: Unexpected indentation.

I think this was fixed in main so a merge with main might fix it.

LGTM. But RTD is failing for some strange reason?
satpy.enhancements._jma_true_color_reproduction:6: ERROR: Unexpected indentation
Maybe someone else has an idea?
Also, a question: Do we need this JPSS-1 entry? Looks a bit odd having it when we don't have anything for 2 & 3?

Ok I found the commit:

No need to merge main. If this is ready then feel free to merge @adybbroe.
