Activate Py 3.10 builds

[joshmoore]

With the freeze for Python 3.11 (https://www.python.org/downloads/release/python-3110b1/), I thought it would make sense to at least try out the latest in a PR. We likely will want to re-evaluate the matrix and perhaps set some items to optional.

Guessing there are missing dependencies

[joshmoore]

🤦🏽 Was reading setup-python documentation but we use setup-conda. I'll keep digging. Worst case, I'll create a simple workflow that uses setup-python.

Edit: yeah, https://anaconda.org/conda-forge/python/labels doesn't seem to have any builds yet.

Pushed directly to origin to test (see https://github.com/zarr-developers/zarr-python/runs/6385329519?check_suite_focus=true) but of course now we're getting into building wheels for numpy, numcodecs, etc.

Likely just too premature, sadly.

[jakirkham]

Yeah unfortunately. There are people starting to look into it

That said, adding Python 3.10 makes a lot of sense

[joshmoore]

Fair enough. Dropped the 3.11b1 build and re-opened.

[jakirkham]

Thanks Josh! 🙏

Also just as a note, we added Python 3.10 to Numcodecs in PR ( zarr-developers/numcodecs#318 )
