The current version of eslint 8 uses the eslintConfig from package.json and is incompatible with eslint 9.

Read, then follow relevant steps of the migration guide - some may not be simple 1-to-1 steps.

The overall outcome is:

• package.json is updated for the right eslint version
• package.json no longer has any eslint directives in it
• package-lock.json only contains only the necessary updates
• an new config file has the config directives
• all lints and tests pass
