xESMF can pull in unimportable ESMPy 8.4.* as dependency

Issue

ESMPy 8.4 changed from specifying authors in both setup.py and the package __init__.py to only in setup.py, using importlib_metadata to grab the metadata from the package dist-info, then moved the whole system to pyproject.toml with no setup.py, during which the list of authors got dropped but the code to get them from dist-info did not. (esmf-org/esmf#58)

At the time, this was not an issue, as importlib_metadata produced a result of None when asked for metadata not provided by the package. This changed to DeprecationWarnings, which prompted a fix before ESMPy 8.5 (esmf-org/esmf#140), and eventually to KeyError, which caused an ImportError.

This is already on the xESMF repo as pangeo-data/xESMF#374

Would it be possible to change the requirements from ESMPy>=8.0 to ESMPy>=8.0, !=8.4.0, !=8.4.1, !=8.4.2? I'm not sure where that gets set, or I'd make the PR myself.

It would exactly what you posted there ,without the spaces after the commas:

ESMPy >=8.0,!=8.4.0,!=8.4.1,!=8.4.2
