Update supported python versions

[altheaden]

conda-forge has recently dropped support for python 3.8 and gained support for python 3.12, so I am updated these versions in this PR.

[altheaden]

I haven't done any testing yet, but I can if desired. I am not sure if it's needed for these changes. I added a file in the ci folder for 3.12, but it's just based on the prior files (3.9 to 3.11), so it might not be set up correctly. I see that CI is failing for 3.12 so maybe there's something else I need to add to this, but I'm not sure what.

@altheaden and I discussed that we will first try to update the GitHub Actions workflow to no longer use mamba/mambaforge and see if that fixes python 3.12.

@altheaden, can you rebase this one now that I merged #65?

[xylar]

@altheaden, I think something is still wrong with the workflow here. This step:

pyremap/.github/workflows/build_workflow.yml

Lines 91 to 95 in eab1c11

	- if: ${{ steps.skip_check.outputs.should_skip != 'true' }}
	name: Install pyremap
	run: |
	conda install --file dev-spec.txt
	python -m pip install .

should use conda create like we do on mache:
https://github.com/E3SM-Project/mache/blob/main/.github/workflows/build_workflow.yml#L96-L102
Could you see if you can make that change? I think using conda install is not behaving well.

@altheaden, I think we might be able to fix the current issues by removing these lines:

          # IMPORTANT: This needs to be set for caching to work properly!
          use-only-tar-bz2: true

Despite the comment, this is no longer needed.

@xylar I assume you have already looked at the changes I made in the build workflow (to match mache's, minus the -e in the pip command). You were right about the "important" line (haha). I think everything should be working now.

[xylar]

Okay, great! I think we're finally in business.

Yes, as I think we discussed, the -e doesn't make sense in CI (thought it does no harm). So this looks great!

Thanks for the hard work on this @altheaden!
