feature request: new rule `no-mock-implementation-throw`

[ysknsid25]

In case vitest ver.4.1, We can write mock implementation throw case:

import { describe, vi } from "vitest";

describe("mock implementation throw", () => {
    test("before vitest v4.1", () => {
        const mockFn = vi.fn().mockImplementation(() => {
            throw new Error("mock error");
        });
        expect(mockFn()).toThrowError("mock error");
    });
    test("aftervitest v4.1", () => {
        const mockFn = vi.fn().mockThrow(new Error("mock error"));
        expect(mockFn()).toThrowError("mock error");
    });
});

So, I believe we recommend mockThrow by new rule like this:

• Issue a warning if mockImplementation is called and contains only a throw statement.
• In the fix, replace mockImplementation with mockThrow.
