`expect.hasAssertion` and `expect.assertions` silently pass outside bdd tests

[WWRS]

Describe the bug

expect.hasAssertion and expect.assertions always pass even when there are not the right number of assertions

Steps to Reproduce

import { expect } from "jsr:@std/expect";

Deno.test("should fail", () => {
    expect.hasAssertions();
});

Deno.test("should also fail", () => {
    expect.assertions(2);
    expect(1).toBe(1);
});

Expected behavior

Both tests fail

Environment

• OS: Win11
• deno version: 2.2.5
• std version: 1.0.14

[WWRS]

This is because assertions tests do not work outside bdd tests. We should probably detect and warn about this.
