fix: allow lifecycle hooks to accept options as second parameter (#24039)

## Summary

Fixes #23133

This PR fixes a bug where lifecycle hooks (`beforeAll`, `beforeEach`,
`afterAll`, `afterEach`) would throw an error when called with a
function and options object:

```typescript
beforeAll(() => {
  console.log("beforeAll")
}, { timeout: 10_000 })
```

Previously, this would throw: `error: beforeAll() expects a function as
the second argument`

## Root Cause

The issue was in `ScopeFunctions.parseArguments()` at
`src/bun.js/test/ScopeFunctions.zig:342`. When parsing two arguments, it
always treated them as `(description, callback)` instead of checking if
they could be `(callback, options)`.

## Solution

Updated the two-argument parsing logic to check if the first argument is
a function and the second is not a function. In that case, treat them as
`(callback, options)` instead of `(description, callback)`.

## Changes

- Modified `src/bun.js/test/ScopeFunctions.zig` to handle `(callback,
options)` case
- Added regression test at `test/regression/issue/23133.test.ts`

## Testing

 Verified the fix works with the reproduction case from the issue
 Added comprehensive regression test covering all lifecycle hooks with
both object and numeric timeout options
 All existing jest-hooks tests still pass
 Test fails with `USE_SYSTEM_BUN=1` and passes with the fixed build
