Missing PyProject schemas

Description of the JSON schema.

pyproject.toml files are missing various schemas under [tool] that can be used. This issue tracks them, the original list can be found at this comment.

• tool.poetry: 45523
• tool.black: 23128
• tool.isort: 16874 (big dataclass, might be easy to transform)
• tool.pytest: 15144 (not sealed, though always in a subtable tool.pytest.ini_options)
• tool.setuptools: 11136
• tool.mypy: 10279
• tool.coverage: 8907 (doesn’t look too hard)
• tool.ruff: 8485
• tool.setuptools_scm: 6034 (easy)
• tool.hatch: 4846
• tool.pylint: 3725 (auto unnesting)
• tool.pyright: 2948
• tool.flit: 2826 (moderate)
• tool.flake8: 1833 (unofficial)
• tool.pdm: 1458
• tool.tox: 1423 (partial support, new keys have recently been added)
• tool.cibuildwheel: 1303
• tool.semantic_release: 1276
• tool.poetry-dynamic-versioning: 982
• tool.maturin: 848 (Maybe easy like Ruff?)

Are you making a PR for this?

No, someone else must create the PR.

Use the original list in the linked comment and pip's pyproject.toml reference as starting points. Review existing SchemaStore entries for the checked tools, then add schemas for the remaining unchecked tools; done means those listed items are supported and can be checked off.
