Simplify dependencies

Remove formatting and linting dependencies from the conda environment
since they are in pre-commit already.

Remove test dependencies from the conda environment
since they are in the Poetry dev dependencies already.

Remove code related to `importlib_metadata` on Python "<3.8".

Remove dependency version constraints for Python "<3.8"
since we only support Python ">=3.8,<3.11".

Remove setuptools and setuptools-scm from build dependencies
since they are superfluous.
