📜 Description

Hey team, I was performing another regular Backstage versions:bump task using the CLI and noticed a conflicting lint configuration.

The CLI version with the issue is ^0.28.2 - even the v.next.2 has this bug.

It happens because the current upstream configuration uses:

    "@typescript-eslint/eslint-plugin": "^6.12.0",
    "@typescript-eslint/parser": "^6.7.2",

But all the plugins are using eslint v8.6.

The quick fix for anyone with this issue is to upgrade both dependencies to v7, e.g.:

    "@typescript-eslint/eslint-plugin": "^7.18.0",
    "@typescript-eslint/parser": "^7.18.0",

Ideally they are all bumped to v8, but the v8 upgrade has more breaking changes I didn't have time to go through.

👍 Expected behavior

Running backstage-cli repo lint always works if not customizations are provided over the upstream configuration.

👎 Actual Behavior with Screenshots

$ backstage-cli repo lint

TypeError: Failed to load plugin 'jest' declared in '.eslintrc.js': Class extends value undefined is not a constructor or null

3. yarn backstage-cli repo lint
