Fix CI: exclude openfeature-provider from root lint and test collection

The openfeature-provider sub-project has its own pyproject.toml and
dependencies. Root pytest was collecting its tests (failing on missing
openfeature SDK), and root ruff was linting it without proper config.

- Add --ignore=openfeature-provider to pytest addopts
- Add extend-exclude for openfeature-provider in ruff config
- Auto-format provider.py and test_provider.py with ruff
