To me I think it would be best for ESLint to support ignoring unknown extensions

Hi @antfu, your thought 100% match what I'm thinking.

If Eslint support a pre-lint hook will be great (eg: {prelint: (file)=>file.endsWith('.ts')}). Or eslint ignores what they cannot lint (but they won't support it because they will treat the files with unknown extensions as js files).

I refactored this PR. Now, not only the ignorePatterns is listed statically, but also this eslint-config will ignore those we cannot lint.

Accepting this PR will not be worse. It make this eslint-config better. No matter Eslint support it or not.
