@alexander-akait The tests are still using eslint 8, we need to update this pr webpack/eslint-config-webpack#29 to switch to eslint 9

[ricardogobbosouza]

We can release and update the tests later.

Hm, I see https://github.com/webpack-contrib/eslint-webpack-plugin/blob/master/.github/workflows/nodejs.yml#L64, am I wrong here, I am thinking we test our plugin with 8 and 9 version

we need to update this pr webpack/eslint-config-webpack#29 to switch to eslint 9

Yeah it is on my radar
