fix: resolve EBADENGINE failures and format CHANGELOG

Exclude Node 18, 19, 21, and 23 for ESLint 10, properly quoting node versions to avoid type mismatch in GitHub Actions matrix exclusions.

Dynamically remove eslint-doc-generator before installing eslint 9+ to prevent EBADENGINE failures due to commander@14 requiring Node >=20.

Format CHANGELOG.md to place removed support under a ### Breaking heading as per v7.0.0 conventions.
