(chore): Update version number inference in dev environments

[flying-sheep]

this PR has two closely related bugfixes:

actually configure version inference correctly

Turns out I messed up in #1680 and put the config into the wrong section, disabling it. So this PR fixes that:

 [tool.hatch.version]
 ...
+raw-options.version_scheme = "release-branch-semver"
 [tool.hatch.build.hooks.vcs]
 ...
-raw-options.version_scheme = "release-branch-semver"

main branch before this PR:

❯ hatch version
0.11.1.dev38+gfaec0f8

(this is wrong as it’s <0.11.3 which is already released)

main branch after this PR:

❯ hatch version
0.12.0.dev40+gffbacdea
❯ hatch build
──── sdist ────
dist/anndata-0.12.0.dev40+gffbacdea.tar.gz
──── wheel ────
dist/anndata-0.12.0.dev40+gffbacdea-py3-none-any.whl

moving that config value to the tool.hatch.version table makes build time versions work as expected (e.g. pip install -e .../anndata in CI), but this PR also fixes a second problem:

make the runtime version use our config

We follow “hatch-vcs-footgun-example”, which updated: maresb/hatch-vcs-footgun-example#4

By using hatchling APIs instead of setuptools_vcs directly, we can make sure the config used by the runtime code is the same used at build time, i.e. in a dev environment, anndata.__version__ gets calculated in the same way as the version embedded in the metadata.

Works well now, and I think it's a bit cleaner that the example you linked to as well. As long as CI passes, should be good.

[flying-sheep]

The example repo is intended to capture best practices around when you do that (i.e. you want to infer the version at runtime). I’ll send a PR that way to capture the plugin error like we do here.
