Interest: adding a `test:eslint-compat` script for upstream ESLint ecosystem tests

👋 Coming over from https://github.com/eslint/eslint/issues/19139 -> https://github.com/eslint/rfcs/pull/127: we're working on an RFC in ESLint core to add "ecosystem tests". We'd like to test popular third-party plugins such as `@eslint-community/eslint-plugin-eslint-comments` as part of ESLint's CI. The goal is to detect API breakages before versions of ESLint or plugins are published that are incompatible with each other. The current version of the RFC suggests: * Plugins would add a `test:eslint-compat` script to run rule tests * ESLint would add a CI job that runs installation, build, and then the `test:eslint-compat` job for each plugin Question: is this something that would be to add in in this repo? The RFC is also still very much open for comments if anybody is interested! 🙂
