Consider adding import/no-unused-modules.

[manovotny]

It'd be super handy to use import/no-unused-modules, but it just reports too many false positives right now.

Desired config:

'import/no-unused-modules': [
    'error',
    {
        missingExports: true,
        unusedExports: true,
    }
],

However:

• unusedExports doesn't take MDX files into account when looking for unused items.
• missingExports flags all kinds of config files, cli scripts, etc.
