add support for Node.js ESM resolution

[piranna]

Similar to eslint-community/eslint-plugin-n#4, add support on import/no-unresolved rule for packages using exports field instead of main. At this moment, https://github.com/import-js/eslint-plugin-import/blob/main/resolvers/node/index.js only supports main and (non standard) module fields.

This will be done automatically once the resolve package supports exports. It won’t be done until then.

At jest it was needed to be added explicitly on Jest v28 after one year and a half waiting it to be added to resolve package, seems it's abandoned...

@piranna it's not abandoned (i'm the maintainer), and yes, i'm aware jest decided not to wait. However, once resolve supports it, jest will likely switch back to using it.
