role-has-required-aria-props

Twelve ARIA roles are incomplete without a particular property. A role="checkbox" with no aria-checked announces itself as a checkbox and then cannot say whether it is ticked:

Div({ role: "checkbox" }); // reported: requires `aria-checked`
Div({ role: "checkbox", "aria-checked": checked }); // fine

The requirement lists come from aria-query — the same data eslint-plugin-jsx-a11y and Svelte's compiler warnings read — rather than being copied into this repo, because the spec's inheritance graph is not something worth hand-maintaining. Some of it is genuinely surprising: slider requires only aria-valuenow, not the whole min/max trio, and separator requires nothing at all.

A props object containing a spread is skipped, since the property this looks for might be arriving inside it.
