Tell codespell to skip fixture / fix pre-commit

[DimitriPapadopoulos]

This will avoid this kind of warnings with codespell 2.2.2:

WARNING: Decoding file using encoding=utf-8 failed: fixture/8/0/11
WARNING: Trying next encoding iso-8859-1

TODO:

• Add unit tests and/or doctests in docstrings
• Add docstrings and API docs for any new/modified user-facing classes and functions
• New/modified features documented in docs/tutorial.rst
• Changes documented in docs/release.rst
• GitHub Actions have all passed
• Test coverage is 100% (Codecov passes)

Maybe we can also get rid of the hard python 3.9 requirement following @mzjp2's advice?

[DimitriPapadopoulos]

I guess I can change python3.9 to python3 in this line:

zarr-python/.pre-commit-config.yaml

Lines 5 to 6 in e8f6fef

	default_language_version:
	python: python3.9

I can do that in a different merge request - to avoid completely rewriting this one.

It's ok if we want to lump these altogether. Maybe we can retitle the PR to capture that

[DimitriPapadopoulos]

I added a second commit to remove the hard python3.9 requirement.

Now pre-commit works on my workstation:

$ pre-commit run codespell
codespell............................................(no files to check)Skipped
