Describe the bug

@nuxt/eslint depends on a version of eslint-config-flat-gitignore that requires eslint@9, but @nuxt/eslint requires 8.57.0. Impossible to satisfy the dependencies without legacy peer deps, or forcing an override.

hey guys, any news on this? it looks like it's not possible to install 0.6 with strict deps :/

Is there any blocker you are still on ESLint v8? There is a small difference between v9.5.0+ and earlier, and it makes eslint-config-flat-gitignore not able to support both versions. An easier solution might be for @nuxt/eslint to drop support for ESLint v8 all - sooner or later, it will eventually happen - if you can share more context of why ESLint v8 is still a requirement for you, we might reconsider that, and decide our support timeline.
