Add support for Typed Linting in script tags about eslint-plugin-astro

[ota-meshi]

Thanks for posting the issue.
We use the ESLint processor for linting client scripts. This assigns a virtual filename so TypeScript cannot get the type information.
I have no idea at the moment to work around this problem. If you have a good idea please let me know.

I think my issue is related to it ...

I created repo to reproduce it - https://github.com/morriq/eslint-astro-issue/

npm install
npm run eslint

should cause

astro-eslint-issue/src/pages/index.astro
  7:8  error  Unsafe member access .then on an `any` value   @typescript-eslint/no-unsafe-member-access
  7:8  error  Unsafe call of an `any` typed value            @typescript-eslint/no-unsafe-call
  7:8  error  Unsafe member access .query on an `any` value  @typescript-eslint/no-unsafe-member-access
  7:8  error  Unsafe call of an `any` typed value            @typescript-eslint/no-unsafe-call

I have definition of it in https://github.com/morriq/eslint-astro-issue/blob/main/src/env.d.ts but somehow parser does not read it
