feat: support named exports in ESM/TS

[43081j]

This adds support for named exports in ESM (whether it be TS or not).

For example:

export const rule: RuleModule = {
  create: () => { ... };
};

Also, exported symbols:

const rule = { ... };

export {rule};

While ESLint plugins are still usually CJS at time of writing this, many are written as ESM sources, and an increasing number are using named exports.

Reviewer notes

You'll want to hide whitespace changes when reviewing this, as prettier reformatted a bunch of it thanks to changing the level of nesting/chaining.

Fixes #375

not sure what you want to do about the testing. since it seems like @aladdin-add already ran the remote tester successfully

@bmish i ran it against:

• eslint-plugin-compat
• eslint-plugin-jest
• TSESLint
• eslint-plugin-vue
• eslint-plugin-prettier

and all seemed well
