No module named importlib

Hi,

upon the new 0.5.5 release you have changed the deprecated dependency of pkg_resources to importlib-metadata. However, I keep getting an error: No module named 'importlib.metadata'

~/anaconda3/envs/core/lib/python3.6/site-packages/umap/init.py in
34 import numba
35
---> 36 from importlib.metadata import version, PackageNotFoundError
37
ModuleNotFoundError: No module named 'importlib.metadata'

I have importlib-metadata installed (version 4.8.2).

Online sources say that the imports should be from importlib_metadata instead of from importlib.metadata.

I believe you need python 3.8 or newer and then importlib.metadata is in the stdlib.

I think UMAP-learn should specify in the requirements in setup.py something like "importlib_resources>=5.10.2; python_version < \"3.9\"" depending on the required Python version.
