I just checked the docs and although it is working we should not use eslint 8.x because its EOL is in October. https://eslint.org/version-support/

We should upgrade eslint to 9.x and try then the config from the docs.
Would you please apply those changes and see if it still works? @mhochsto

PS: I also merged the changes from main so its up to date =)

Due to incompatibilities with our current eslint plugin infrastructure, we should stick to [email protected] for the time being.
