build(python): remove setuptools_scm dependency

We update version in several .toml and .json files
on every release anyway, so updating pyproject.toml is easy.

setuptools_scm makes it more difficult to build
python packages for software distributions
because it requires full git checkout
with tags rather than just a worktree.
It is also possible to remove or move tags
after the release, so git revision no longer
pins python package version if setuptools_scm is used.
