The main change in ESLint v9 is the move to flat configs, which are .js files rather than .json. We should eventually switch to a flat config in a separate PR first, they're supported in v8. Once the config is updated, this PR will pass tests and merge automatically. We currently use the following ESLint plugins...

• eslint-config-mdcs
• eslint-plugin-compat
• eslint-plugin-html
• eslint-plugin-import

... but none of them yet support the flat configs required in ESLint 9, so I think this will be blocked for a while.

Let's block Renovate bot from making PRs for ESLint, until that situation improves:

• chore(lint): Add eslint to renovate bot's denylist #28356

I got partway through the migration to a flat config before hitting the issues above. In case it's helpful next time, here's the partially-upgraded config:

eslint.config.js

import globals from "globals";

export default [
  {
    files: ["**/*.js"],
    extends: ["mdcs", "plugin:compat/recommended"],
    plugins: ["html", "import"],

    },
    languageOptions: {
