🐛 BUG: astro check reports false positive unused variable when variable is used in Astro.redirect

[fengelniederhammer]

Describe the Bug

astro check reports false positive when using import in return Astro.redirect( --> here <-- ).

For example here, it will report that MyObject is unused:

---
import { MyObject } from '../object';

return Astro.redirect(
    MyObject.asdfasdf,
);
---

This works as expected though (astro check recognizes MyObject as being used):

---
import { MyObject } from '../object';

let value = MyObject.asdfasdf;
return Astro.redirect(value);
---

A real-world example can be found in https://github.com/GenSpectrum/dashboards/blob/09e505a0bd82a87cf2d460dd3d70fff063eb1b0d/website/src/pages/covid/index.astro

Steps to Reproduce

1. npm create astro@latest, npx astro check to install @astrojs/check - yields ATM:

  "dependencies": {
    "@astrojs/check": "^0.9.4",
    "astro": "^5.0.4",
    "typescript": "^5.7.2"
  }

2. src/pages/index.astro:

---
import { MyObject } from '../object';

return Astro.redirect(
    MyObject.asdfasdf, // access a key that does not exist
);
---

3. src/object.ts:

export const MyObject = {
    helloWorld: 'Hello World!',
}

4. npx astro check:

$ npx astro check
11:12:10 [content] Syncing content
11:12:10 [content] Synced content
11:12:10 [types] Generated 26ms
11:12:10 [check] Getting diagnostics for Astro files in .../dashboards/astro/square-series...
src/pages/index.astro:2:1 - warning ts(6133): 'MyObject' is declared but its value is never read.

2 import { MyObject } from '../object';
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Result (4 files): 
- 0 errors
- 0 warnings
- 1 hint

5. It reports a false positive on an unused variable (it is used - obviously). But it doesn't report the access to the non-existent key.
