viteConfig type in defineConfig is not correct

[FranciscoMoretti]

Hey, thanks for creating this awesome package!

I've found that the viteConfig prop as part of defineConfig doesn't reflect the actual configuration accepted. In fact, the only property that it expects is test. However, it works anyway 👍. So I'm assuming it's a type issue.

This is the config I used. Had to add a plugin for path aliases.

import tsconfigPaths from 'vite-tsconfig-paths'

export default defineConfig({
  viteConfig: {
    // @ts-expect-error this is actually the correct way to pass vitest config
    plugins: [tsconfigPaths()],
  },
});

Here's the TS error

Object literal may only specify known properties, and 'plugins' does not exist in type '{ test?: StrictOmit<UserConfig, "mode" | "include" | "setupFiles" | "testTimeout" | "maxConcurrency" | "browser" | "config" | "watch" | "reporters" | "testNamePattern"> | undefined; }'.ts(2353)
types.d.ts(125, 9): The expected type comes from property 'viteConfig' which is declared here on type 'Config'

Version: "1.0.0-beta.8"

Yes, I found this while implementing it but couldn't find a decent way to type it without adding vite as a dependency, which I don't want.

Would happily accept a PR for this.

For now, you can do this pattern and it works:
