Default export should match filename

[amannn]

See the discussion in import-js/eslint-plugin-import#662 and filenames/match-exported of https://www.npmjs.com/package/eslint-plugin-filenames.

However with the current story with peer dependencies it's a bit painful to add new plugins.

Related, it would be nice to ensure that imports match filenames.

There are some exceptions to this:

E.g. in Next.js you have index.page.tsx but neither Index nor IndexPage work for the current state of eslint-plugins-filenames.
