Issue:
Redirect in action does not respect status code
### Describe the bug

If a form action redirects, the status code passed into `redirect(status, location)` is always replaced with `303`. 

### Reproduction

https://stackblitz.com/edit/sveltejs-kit-template-default-cq96ae?file=src/routes/+page.server.js

Click the button and look at the console logs. You'll see a 303 redirect even though we passed in "302".

### Logs

```Shell
Status code: 200
Status code: 303
Status code: 200
```

    vite: ^4.0.0 => 4.0.1
```


### Severity

serious, but I can work around it

### Additional Information

I'm guessing this isn't a big deal for most of the client rendered apps out there. But if there are any server rendered apps that rely on non-303 redirects from a form action, e.g. a Permanent redirect, this will be important.

- [x] This message body should clearly illustrate what problems it solves.
- [x] Ideally, include a test that fails without this PR but passes with it.

### Tests
- [x] Run the tests with `pnpm test` and lint the project with `pnpm lint` and `pnpm check`

### Changesets
- [x] If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running `pnpm changeset` and following the prompts. All changesets should be `patch` until SvelteKit 1.0
