vite-plus/test module identities break vitest type augmentations

[joknoll]

Describe the bug

When using Vite+ test imports, third-party Vitest type augmentations do not apply because the module specifiers differ from vitest and vitest/browser.

I have a small demo repo as a reproduction. In this repo I get type errors for the test/repro.browser.test.ts file.

Reproduction

Steps to reproduce

Running vp check results in these errors:

  × typescript(TS2339): Property 'render' does not exist on type 'BrowserPage'.
   ╭─[tests/browser/repro.browser.test.ts:7:29]
 6 │ test("reproduces missing Vite+ type augmentations", async () => {
 7 │   const screen = await page.render(Repro, { label: "hello" });
   ·                             ──────
 8 │
   ╰────

  × typescript(TS2339): Property 'element' does not exist on type 'ExpectStatic'.
    ╭─[tests/browser/repro.browser.test.ts:9:16]
  8 │
  9 │   await expect.element(screen.getByRole("heading", { name: "hello" })).toBeVisible();
    ·                ───────

@joknoll https://github.com/joknoll/vite-plus-vitest-type-aug/pull/1/changes right now you need to add vitest into devDependencies to resolve this, otherwise pnpm overrides field won’t take effect.
I’m still looking for a better configuration approach.
