ESLint v8.31.0 released

Highlights

The no-underscore-dangle rule gained two new options: allowInArrayDestructuring and allowInObjectDestructuring. Both of these default to true to allow dangling underscores in array and object destructuring for backwards compatibility. Set them to false to check for dangling underscores in destructuring assignments.
