ci(type-check): add ESLint 8 and 9 to published types matrix

Treat ESLint 7 as the only @types/eslint special case and use built-in ESLint types for 8+. Keep the existing ESLint 10 peer-dependency workaround and TS >= 5 restriction intact.

This increases the type-check matrix from 48 to 120 jobs, so CI runtime will go up.
