module_available gives inaccurate version info

[d-v-b]

What is your issue?

importlib.metadata.version is not always right:

>>> from importlib.metadata import version
>>> version('zarr')
'2.16.2.dev35+dirty'
>>> import zarr
>>> zarr.__version__
'3.0.5.dev88+g8af0ce42'

see an older discussion of this behavior here

I don't know if there's a fix besides try... except around an import statement? But this issue prevents xarray from seeing my local zarr v3 install, which prevents me from debugging zarr v3 issues.

This is almost certainly due to missing tags.

good evidence for the "missing tags" theory! Closing, thanks @dcherian
