[BUG]: drizzle-kit pull doesn't generate the schema file in defineConfig

### Report hasn't been filed before.

- [x] I have verified that the bug I'm about to report hasn't been filed before.

### What version of `drizzle-orm` are you using?

0.42.0

### What version of `drizzle-kit` are you using?

0.31.0

### Other packages

_No response_

### Describe the Bug

drizzle.config.js

```
import { defineConfig } from 'drizzle-kit'

export default defineConfig({
out: './drizzle',
schema: './src/db/schema.js',
dialect: 'postgresql',
dbCredentials: {
url: process.env.DATABASE_URL
}
})
```

if I do

`npx drizzle-kit pull`

it generates a file in `./drizzle/schema.ts` shouldn't this be in `./src/db/schema.js`?
