Description

The @liferay/eslint-plugin package uses babel-eslint as a parser, but doesn't list it as a dependency nor as a peer dependency.

I don't mind installing it in my package, but I would like for it be documented at least as a peer dependency so NPM can give me warnings when its missing.

Desired behavior: I'm able to use @liferay/eslint-plugin's general configuration and run ESLint with it.

Current behavior:

Oops! Something went wrong! :(

ESLint: 7.32.0

Error: Failed to load parser 'babel-eslint' declared in '.eslintrc.json » plugin:@liferay/general': Cannot find module 'babel-eslint'
