• That issue was marked as accepting prs
• Steps in Contributing were taken

Overview

Since eslint v9 is a major version, I added it to peerDependencies to avoid a warning message when installing eslint and typescript-eslint.

yarn classic:

$ yarn add -D typescript-eslint
yarn add v1.22.19

We don't currently support eslint v9 - hence the issue you linked. We are working to build out support and will update the version range when it is ready.
