remove 3.7, add 3.11 & 3.12

[yibeichan]

python 3.7 kept failing GA with the following error:

Run actions/setup-python@v2
  with:
    python-version: [3](https://github.com/ReproNim/reproschema-py/actions/runs/8881434819/job/24383768417#step:3:3).7
    token: ***

I guess it's time to say goodbye

add 3.12 as well

[yibeichan]

okay great, 3.11 was okay but 3.12 failed. it seems that we need to fix something

[Remi-Gau]

error seems related to this (versioneer related)

pydata/pandas-datareader#969

My 2 cents: stick to 3.11 in this PR, modernize the packaging (pyproject.toml + build with hatchling-vcs to drop versionner) and support 3.12

[Remi-Gau]

modernize the packaging (pyproject.toml + build with hatchling-vcs to drop versionner)

I can take care of this

sounds good! removed 3.12. I don't even know what "hatchling-vcs to drop versionner" means

perhaps just follow the versioneer steps in their readme. i think that should work to update versioneer quite easily. also may need to update version of auto in the github workflows.

[yibeichan]

yay, updated versioneer works. i'm going to merge this one
