Subject: [PATCH] fix(linter): false positive with unknown plugins when
 unmatched eslint rule (#12285)

What's happening is some config files have rules such as:
`constructor-super`, this gets mapped to `unknown_plugin/constructor-super`, which means we try to load the "unknown_plugin" (which doesn't exist, hence causing the error).

Since using only the rule's name as the rules identifier in the config file is only supported for eslint rules, we can just map this back to the `eslint` plugin
