Repos which use the eslint config published by this repo run into a problem where eslint exits with code 1. For example: https://github.com/the-guild-org/website/actions/runs/15630837568/job/44034593226

It looks like the issue is related to upgrade of eslint-plugin-unicorn.

This requires ESM dynamic import, which only works fully on ESLint 9, which is defined as a requirement (although this is missed at install?)

It was updated in the-guild configs here: 20476f5

Downgrading it from 57 to 56 should resolve the eslint failing.

I have also looked at updating to eslint 9. (Renovate tried to do this but was blocked)

I have done the migration work locally for the website repo, but it still uses 8 because that's what's defined as required by @theguild/eslint-config.
So, that approach is a dead end unless @theguild/eslint-config updates to 9 also.
This would require all repos that use it to then also migrate to 9 if they update their version.
